Refactor CPU interface to allow the implementation of other CPU emulators (#3362)
* Refactor CPU interface

* Use IExecutionContext interface on SVC handler, change how CPU interrupts invokes the handlers

* Make CpuEngine take a ITickSource rather than returning one

The previous implementation had the scenario where the CPU engine had to implement the tick source in mind, like for example, when we have a hypervisor and the game can read CNTPCT on the host directly. However given that we need to do conversion due to different frequencies anyway, it's not worth it. It's better to just let the user pass the tick source and redirect any reads to CNTPCT to the user tick source

* XML docs for the public interfaces

* PPTC invalidation due to NativeInterface function name changes

* Fix build of the CPU tests

* PR feedback

Interrupt GPU command processing when a frame's fence is reached. (#1741)
* Interrupt GPU command processing when a frame's fence is reached.

* Accumulate times rather than %s

* Accurate timer for vsync

Spin wait for the last .667ms of a frame. Avoids issues caused by signalling 16ms vsync. (periodic stutters in smo)

* Use event wait for better timing.

* Fix lazy wait

Windows doesn't seem to want to do 1ms consistently, so force a spin if we're less than 2ms.

* A bit more efficiency on frame waits.

Should now wait the remainder 0.6667 instead of 1.6667 sometimes (odd waits above 1ms are reliable, unlike 1ms waits)

* Better swap interval 0 solution

737 fps without breaking a sweat. Downside: Vsync can no longer be disabled on games that use the event heavily (link's awakening - which is ok since it breaks anyways)

* Fix comment.

* Address Comments.

Rewrite scheduler context switch code (#1786)
* Rewrite scheduler context switch code

* Fix race in UnmapIpcRestorePermission

IPC refactor part 2: Use ReplyAndReceive on HLE services and remove special handling from kernel (#1458)
* IPC refactor part 2: Use ReplyAndReceive on HLE services and remove special handling from kernel

* Fix for applet transfer memory + some nits

* Keep handles if possible to avoid server handle table exhaustion

* Fix IPC ZeroFill bug

* am: Correctly implement CreateManagedDisplayLayer and implement CreateManagedDisplaySeparableLayer

CreateManagedDisplaySeparableLayer is requires since 10.x+ when appletResourceUserId != 0

* Make it exit properly

* Make ServiceNotImplementedException show the full message again

* Allow yielding execution to avoid starving other threads

* Only wait if active

* Merge IVirtualMemoryManager and IAddressSpaceManager

* Fix Ro loading data from the wrong process

surfaceflinger: Disable async buffer (#1603)
This fix a mistake I made during my original reimplementation of SurfaceFlinger by disabling async buffer.

This fix a memory corruption on Super Mario All-Stars 3D (Super Mario Sunshine & Super
Mario Galaxy now go ingame).

Thanks to @gdkchan for tracing the memory corruption.

Improved Logger (#1292)
* Logger class changes only

Now compile-time checking is possible with the help of Nullable Value
types.

* Misc formatting

* Manual optimizations

PrintGuestLog
PrintGuestStackTrace
Surfaceflinger DequeueBuffer

* Reduce SendVibrationXX log level to Debug

* Add Notice log level

This level is always enabled and used to print system info, etc...
Also, rewrite LogColor to switch expression as colors are static

* Unify unhandled exception event handlers

* Print enabled LogLevels during init

* Re-add App Exit disposes in proper order

nit: switch case spacing

* Revert PrintGuestStackTrace to Info logs due to #1407

PrintGuestStackTrace is now called in some critical error handlers
so revert to old behavior as KThread isn't part of Guest.

* Batch replace Logger statements

SurfaceFlinger: fix some bugs (#1262)
* SurfaceFlinger: fix some bugs

This fixes some bugs in the current implementation and make it closer to
the real implementation.

* Fix align of some variables

Thog da3fd3f71b surfaceflinger: FreeBufferLocked doesn't reset the graphic buffer
That's the job of the user on Horizon (via SetPreallocatedBuffer).

SurfaceFlinger: fix SetPreallocatedBuffer correctness (#1153)
Nintendo sets the buffer count in SetPreallocatedBuffer too.

This fix triple buffering on all games and finally fix SSBU flickering.

SurfaceFlinger v2 (#981)
* Rewrite SurfaceFlinger

Reimplement accurately SurfaceFlinger (based on my 8.1.0 reversing of it)

TODO: support swap interval properly and reintroduce disabled "game vsync" support.

* Some fixes for SetBufferCount

* uncomment a test from last commit

* SurfaceFlinger: don't free the graphic buffer in SetBufferCount

* SurfaceFlinger: Implement swap interval correctly

* SurfaceFlinger: Reintegrate Game VSync toggle

* SurfaceFlinger: do not push a fence on buffer release on the consumer side

* Revert "SurfaceFlinger: do not push a fence on buffer release on the consumer side"

This reverts commit 586b52b0bfab2d11f361f4b59ab7b7141020bbad.

* Make the game vsync toggle work dynamically again

* Unregister producer's Binder object when closing layer

* Address ripinperi's comments

* Add a timeout on syncpoint wait operation

Syncpoint aren't supposed to be waited on for more than a second.

This effectively workaround issues caused by not having a channel
scheduling in place yet.

PS: Also introduce Android WaitForever warning about fence being not
signaled for 3s

* Fix a print of previous commit

* Address Ac_K's comments

* Address gdkchan's comments

* Address final comments
