4b80e1f91c Use libcxx from LLVM Project submodule
The version of libcxx shipped with Android NDK is fairly outdated and doesn't contain several features we desire such as C++ 20 ranges. This has been fixed by using libcxx directly from the LLVM Project which has been added as a submodule and can be updated independently of NDK.

82154f3ef6 Upgrade AGP to 7.1.0-beta01 & NDK to 24.0.7856742
We've moved to using a beta AGP as `7.0.2` is breaks `clangd` and other C++ features on Beta/Canary Android Studio. NDK was additionally updated with `mbedtls` to fix warnings caused by it alongside some other minor fixes to code for newer versions of libcxx.

The new AGP has a bug where it does not look for executables specified in `android_gradle_build.json` in `PATH` that includes `ninja` which is provided by the `ninja-build` package on the system rather than Android SDK's CMake on GitHub Actions (Ubuntu 20.04). This has been fixed by symlinking `/usr/bin/ninja` to the project root which is searched in for the `ninja` executable.

10ed5bf418 Silence errors from libraries
Library headers would produce errors that are out of our control and as a result of that, we just want to ignore this. This is possible by including the offending headers as system headers, compilers don't emit any warnings arising from them. This was extended to all libraries rather than just those which currently emitted warnings for consistency's sake.

239d2625e2 Introduce CommandExecutor + Implement ClearBuffers + More RT Formats
This commit introduces the `CommandExecutor` which is responsible for creating and orchestrating a Vulkan command graph comprising of `CommandNode`s that construct all the objects required for rendering. As a result of the infrastructure provided by `CommandExecutor`, `ClearBuffers` could be implemented and be appropriately utilized.

A bug regarding scissors was also determined and fixed in the PR, the extent of them were previously inaccurate and this has now been fixed.

Note: We don't synchronize any textures from the guest for now as this would override the contents on the host, this'll be fixed with the appropriate write tracking but it also results in a black screen for anything that writes to FB

bee28aaf0d Validation Layer Filter + Fix Texture, GPU & PresentationEngine bugs
This commit implements a filter by type for any validation layer output, this allows filtering out any logs which may be unnecessary and additionally triggering a breakpoint as required. 

An issue concerning the `NDEBUG` flag never being set was fixed, it's now supplied as a release compiler flag. The issue can manifest itself by always relying on a validation layer even though it shouldn't on release, this is why the validation layer was mistakenly disabled entirely previously by using `#ifndef` rather than `#ifdef`.

An issue with the initial layout of a texture being supplied as neither `VK_IMAGE_LAYOUT_UNDEFINED` or `VK_IMAGE_LAYOUT_PREINITIALIZED` was fixed, these cases are now handled by transitioning to those layouts after creating the image rather than supplying it within `initialLayout`.

Another issue was fixed regarding not maintaining a transformation after a surface has been destroyed and recreated existed and manifested itself when the user would go out of the app and come back in, they would see the surface having an identity transformation rather than the desired one.

54908afc44 Texture GMMU Address Resolution + Refactor Maxwell3D::CallMethod
Fixes bugs with the Texture Manager lookup, fixes `RenderTarget` address extraction (`low`/`high` were flipped prior), refactors `Maxwell3D::CallMethod` to utilize a case for the register being modified + preventing redundant method calls when no new value is being written to the register, and fixes the behavior of shadow RAM which was broken previously and would lead to incorrect arguments being utilized for methods.

Implement the groundwork for the texture manager to be able to report basic overlaps and be extended to support more in the future. The Maxwell3D registers `RenderTargetControl`, `RenderTarget` and a stub for `ClearBuffers` were implemented. 

A lot of changes were also made to `GuestTexture`/`Texture` for supporting mipmapping and multiple array layers alongside significant architectural changes to `GuestTexture` effectively disconnecting it from `Texture` with it no longer being a parent rather an object that can be used to create a `Texture` object.

Note: Support for fragmented CPU mappings hasn't been added for texture synchronization yet

All of these issues have been solved by moving to a git submodule tied to the official Mbed TLS GitHub repository.

36547cd5dc Redesign Texture Class + Improve Presentation Engine
This commit reworks the `Texture` class to include a Vulkan Image backing that can be optionally owning or non-owning and swapped in with consideration for Vulkan image layout, it also adds CPU-sided synchronization for the texture objects with FenceCycle. It also makes the appropriate changes to `PresentationEngine` and `GraphicBufferProducer` to work with the new `Texture` class while setting the groundwork for supporting swapchain recreation. It also fixes a log in `IpcResponse` and improves the display mode selection algorithm by further weighing refresh rate.

2143b43068 Vulkan PhysicalDevice + Device Initialization + Report Accurate Version
Vulkan Device initialization is handled now, it supports required extensions but support for optional extensions/features/properties will come in later when we require those. In addition, we now correctly report the version of Skyline to Vulkan which can be accessed from debugging tools. 

There's also a minor change regarding the search pattern for `SkylineLibraries` which now only searches in headers of libraries and it also explicitly excludes the redundant `vulkan.hpp` from the `Vulkan-Headers` repository.

8ceed74371 Vulkan Instance + Validation Layer + Debug Report Initialization
The GPU class has been extended in this for Vulkan initialization, this is done to the point of initializing the instance alongside loading in `VK_LAYER_KHRONOS_validation` which is also now packed into all Debug APKs for Skyline. In addition, `VK_EXT_debug_report` is also initialized and it's output is piped directly into the Logger. 

A minor change regarding the type of the `Fps` and `Frametime` globals was changed to `skyline::i32`s which is a more suitable type due to those having a smaller chance of overflowing while being signed as Java doesn't have unsigned integral types.

0c29f982d5 Replace skyline-emu/VkHpp with KhronosGroup/Vulkan-Hpp
We used a custom version of Vulkan-Hpp which split the files a lot prior to avoid any developers needing to manually set IDE settings for IntelliJ to work but this wasn't practical due to how it required modifications to Vulkan-Hpp's generator which would make maintenance extremely difficult. It was determined that we should just add the requirement for changing the IDE settings and use Vulkan-Hpp directly.

ba418976b0 Implement full timezone service support
This serves as an extension to the initial time commit and combined
they provide a complete implementation of everything application facing
in time.

psc:ITimeZoneService and glue:ITimeZoneService are used to convert
between POSIX and calendar times according to the device location.
Timezone binaries are used during the conversion, details of them can
be read about in the previous commit.

This is based off my own glue RE and Thog's time RE.

34cb0b49e8 Implement the entirety of time services
This reimplements our time backend to be significantly more accurate to
the real PSC and provides complete implementations for every time IPC
allowing many newer games to work properly.

Time is unique in its use of glue services, the core sysmodule is fully
isolated and doesn't interface with any other services. Glue is instead
used where that is needed (e.g. for fetching settings), this distinction
is also present in our implementation.

Another unique feature of time is its global state, as time is
calibrated from the start of the service its state cannot be lost as
that would result in the application offsetting time incorrectly
whenever it closed a session.

A large proportion of this is based off of Thog's 9.0.0 PSC reversing.

a53d6266c7 Implement a basic NSP loader
An NSP (Nintendo Submission Package) is effectively a PFS0 containing
NCAs, there are also tickets and a CNMT file which contains metadata
about updates. The current implementation is very basic and only
support Control and Program NCAs which is enough for loading games.

Support for updates and dlc will be added at a later date.

a5513bd7e6 Implement an NCA parser and loader
Nintendo Content Archives are used to store the assets, executables
and updates of applications. They support holding either a PFS0 or a
RomFS.

An NCA's ExeFS can be loaded by placing each NSO sequentially into
memory, starting with rtld which will link them together.

Currently only decrypted NCAs are supported, encryption and BKTR
handling will be added at a later time.

db64f53cfb Implement filesystem backends for RomFS and Partition FS
RomFS is a hierarchial filesystem where each level is made up of a
linked list of files and child directories. It is used in NCAs to store
the applications icon as well as by applications themselves for
accessing assets.

Partition FS encapsulates both the HFS0 found in XCIs and the PFS0 used
for ExeFS images and NSPs, it is purely file based and has no support at
all for directories aside from the root.

3a23ec06a4 Implement NSO loader
The NSO format is used by all retail games and some homebrew. It
supports compressing sections with lz4 and dynamic linking through the
use of rtld.

bf46293fc7 Commonise executable loading infrastructure
Mapping and writing segments into memory is now handled by a common
function that can be shared between all loaders. All they need to do now
is to pack each segment into a common struct.

Fixes for control IPC (#57)
* Correctly handle -WithContext IPC Requests

They should be treated the same as the non WithContext variants.

* Only send domain data on non-control IPC responses

Control IPC doesn't make use of domains so we shouldn't send extra data
in the response.

* Add the IStorage implementation to CMakeLists

5c103ce9a6 Introduce basic VFS backing system together with two implementations
- The backing system provides a flexible way to access a a region of
   abstract memory.

- It is currently barebones and only has support for reading data but
   this will be expanded as necessary.

The current implementations are:
- OsBacking - A backing that abstracts a linux file descriptor
- RegionBacking - A backing that creates a region from a portion of an
   existing one

820bbaede5 Fix occurrence of multiple headers in game list + Make TinyXML2 Static
This commit mainly fixes multiple headers in the game list, which was caused by using the wrong variable for the recursive function. In addition, it makes TinyXML2 statically linked to libskyline which makes it the lone shared objects present in APKs.

618353c1fa Move to linking libraries statically
We used to link libraries dynamically before, this has obvious disadvantages and extra run-time overhead. Linking them statically instead has a lot of benefits as memory allocations and such don't need to be done independently, interaction with external libraries should be faster in general due to functions not being needed to be called virtually.

This commit addresses the incorrect hierarchy of the GPU and refactors them at the same time. Now, the hierarchy much closely matches HOS. This commit also introduces a texture classes, albeit they're not complete and only partially implemented.
