670a80d2c4 Create a memory chunk for the stack shared memory
As the stack is automatically mapped in the guest by `clone` we do not
need to explicitly map it. This adds a flag to solve the issue.

Also mark the stack as stack rather than reserved.

7884a60679 Make regions public members of the memory class and drop the type enum
There isn't really much benefit in having a getter or an enum, so drop
it.

6329537a9e Correct audren event handling and zero the sample buffer
Not zeroing the sample buffer causes issues when a voice is started but
is playing no samples. The system event handling was also reworked
according to Thog's info.

9ef25a6beb IPC bug fixes
This fixes two bugs in IPC that were discovered when running Puyo Puyo
Tetris.

The CloneCurrentObject control IPC will now correctly return the handle
of the newly created object through move handles, rather than pushing it
as a result.

The size array of u16s with the sizes of each C buffer is now taken into
account when reading them. Before this change C buffers were entirely
broken.

This gives some useful warnings for less significant issues.
Warnings for reordering are left disabled as they are rather pedantic

801382e43a Implement pl:u for accessing shared fonts
Fonts are stored in an array of TTF data with an 8 byte header
containing a magic and an XOR'd length. Instead of requiring users to
provide original Nintendo fonts we pack open source replacements.
They are generated with the scripts here
https://github.com/FearlessTobi/yuzu_system_archives. All the fonts are
licenced under the Open Font or Apache 2 License so we can include them
all freely.

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.

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

8d470d3218 Introduce basic RomFS support
This commit adds support for reading the RomFS data from an NRO and
obtaining an IStorage handle to it through 'OpenDataStorageByCurrentProcess'.
There is currently only support for reading and no support
for enlarging or writing.

Also fixup a few capitalisation issues.

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
