3f7373209a Move Guest GPU into SoC Directory
We decided to restructure Skyline to draw a layer of separation between guest and host GPU. We're reserving the `gpu` namespace and directory for purely host GPU and creating a new `soc` directory and namespace for emulation of parts of the X1 SoC which is currently limited to guest GPU but will be expanded to contain components like the audio DSP down the line.

ae68009f9b Extend Perfetto Tracing
Add Tracing for SVCs, Services, NVDRV, and Synchronization Primitives. In addition, fix `TRACE_EVENT_END("guest")` being emitted when a signal is received while being in the guest rather than host which would cause an exception. This commit also disables warnings for the Perfetto library as we do not control fixing them.

fe5061a8e0 Address CR Comments (#132) + Change Core Migration API
This addresses all CR comments including more codebase-wide changes arising from certain review comments like proper usage of its/it's and consistent contraction of it is into it's. 

An overhaul was made to the presentation and formatting of `KThread.h` and `LoadBalance` works has been superseded by `GetOptimalCoreForThread` which can be used alongside `InsertThread` or `MigrateToCore`. It makes the API far more atomic and neater. This was a major point of contention for the design prior, it's simplified some code and potentially improved performance.

0ea02f2d56 Fix Non-Cooperative Core Migration + Fix yieldWithCoreMigration + Improve Mutex Locking in ConditionalVariableWait
The case of a thread not being in the core queue during a non-cooperative core affinity change would break things as the thread was non-conditionally removed and inserted, this has been fixed by adding a check to see if the thread exists in the core's queue prior to migration. In addition, `yieldWithCoreMigration` was broken by the previous commit as the fallthrough was intentional and removing it cause core migration without a yield which led to breakage in certain circumstances. The mutex locking logic was also improved in `ConditionalVariableWait` to use atomics in a more effective manner with less atomic operations being performed overall.

11c5f50d37 Use likelihood attributes in NCE + Fix System Version + SVC improvements
The SVCs improvements are as follows:
* Make SVC logs more concise for:
* * `SleepThread`
* * `ClearEvent`
* * `CloseHandle`
* * `ResetSignal`
* * `WaitSynchronization` (Special case for single handle)
* * `ArbitrateLock`
* * `ArbitrateUnlock`
* * `WaitProcessWideKeyAtomic`
* * `SignalProcessWideKey`
* Fix unintentional fallthrough into `yieldWithoutCoreMigration` from `yieldWithCoreMigration` in `SleepThread`
* Return `result::InvalidState` when an unsignalled handle is reset in `ResetSignal`
* Return `Result{}` (Success) in `CancelSynchronization`
* Do not return `result::InvalidCurrentMemory` in `ArbitrateLock` as it's not a failure condition
* Make `count` in `WaitProcessWideKeyAtomic` a `i32` from a `u32`, zero and all negative values result in waking all waiters

20bdda6a63 Support Core Migration for Running External Thread
We did not support migration of threads which were running in a non-cooperative manner, this was partially due to the dependence on per-core conditional variables rather than per-thread which made this harder to do programmatically. This has been fixed by moving to per-thread cvars and therefore the limitation can be removed, this feature is used by Unity games.

198f32de51 Disable uninitialized variable clang-tidy warnings
These create a lot of clutter when something was left uninitialized
because it would be overwritten anyway.

668f623256 Implement Exceptional Signal Handler + Fix Destruction Behavior
An exceptional signal handler allows us to convert an OS signal into a C++ exception, this allows us to alleviate a lot of crashes that would otherwise occur from signals being thrown during execution of games and be able to handle them gracefully.

773ee25e5a Refactor Common
This refactored common by:
* Moving out as many constants to class/function local scopes from being declared in `common`
* Spacing out common and any function to which a constant was moved out to
* Fixing comments here and there
In addition, some naming inconsistencies were fixed as well.

This commit causes Android Studio to use the .clang-tidy file for configuration and removes madvise DO_FORK/DONT_FORK calls as they cause problems on many devices and are mostly unnecessary.
