This fix a deadlock on DoDonPachi Resurrection when starting a new game
* Address gdkchan's comment

This commit adds support for 8.x thread pinning changes and implement SynchronizePreemptionState syscall.
Based on kernel 13.x reverse.
* Address gdkchan's comment
* kernel: fix missing critical section leave in SetActivity
Fix Unity games
* Implement missing bits on the interrupt handler and inline update pinning function as it cannot be generic
* Fix some bugs in SetActivity and SetCoreAndAffinityMask
* Address gdkchan's comments
* kernel: Define InfoTYpe and make it less obscure when reading GetInfo
Also map ThreadTickCount to 25 instead of 0xF0000002 like 13.x kernel.
* kernel: Implement GetInfo IsApplication
* kernel: Implement GetInfo FreeThreadCount
* kernel: Fix sleep timing accuracy
This commit corrects some mistake while comparing reversing of kernel
13.x with our own.
WaitAndCheckScheduledObjects timing accuracy was also improved.
* Make KTimeManager.WaitAndCheckScheduledObjects spin wait for sub milliseconds
Fix performance regression on Pokemon Let's Go games and possibly
others.
* Address rip's comment
* kernel: Fix issues with timeout of -1 (0xFFFFFFFF)
Fixes possible hang on Pokemon DP and possibly others
Add basic support for the CFI value being passed in X18 since 11.0.0 by the official kernel.
We do not implement any random generator atm in the kernel and as such the KSystemControl.GenerateRandom function is stubbed
* kernel: Clear pages allocated with SetHeapSize
Before this commit, all new pages allocated by SetHeapSize were not
cleared by the kernel.
This would cause undefined data to be pass to the userland and possibly
resulting in weird memory corruption.
This commit also add support for custom fill heap and ipc value (that is also
supported by the official kernel)

Add an EventSource which measures the amount of unmanaged bytes
allocated by AddressTable<T> instances.
dotnet-counters monitor -n Ryujinx --counters ARMeilleure
* Add `AllowLcqInFunctionTable` optimization toggle
This is to reduce the impact this change has on the test duration.
Before everytime a test was ran, the FunctionTable would be initialized
and populated so that the newly compiled test would get registered to
it.
* Implement unmanaged dispatcher
Uses the DispatchStub to dispatch into the next translation, which
allows execution to stay in unmanaged for longer and skips a
ConcurrentDictionary look up when the target translation has been
registered to the FunctionTable.
* Remove redundant null check
* Tune levels of FunctionTable
Uses 5 levels instead of 4 and change unit of AddressTableEventSource
from KB to MB.
* Use 64-bit function table
Improves codegen for direct branches:
mov qword [rax+0x408],0x10603560
- mov rcx,sub_10603560_OFFSET
- mov ecx,[rcx]

- mov rdx,JIT_CACHE_BASE
- add rdx,rcx

- mov eax,[rcx+rax*4]
- mov eax,eax
- mov rcx,JIT_CACHE_BASE
- lea rax,[rcx+rax]
+ mov rax,[rcx+rax*8]
mov rcx,rbx
* Remove `JitCacheSymbol` & `JitCache.Offset`

* Move documentation, fix tests.
* Cleanup uniform buffer update stuff.
* Remove unnecessary assignment.

On by default. Would be good to turn this off for untrusted code (homebrew, exefs mods) and give the user the option to turn it on manually, though that requires some UI work.

They have issues due to current .NET limitations, so the meilleure one fully replaces them for now.

* Remove readonly keyword, as this is now modified.
* Use a local variable for the signal handler rather than a register.

Doesn't do anything yet
* Call invalid access handler on unmapped read/write.
Same rules as the regular memory manager.
* Make unsafe mapped memory its own MemoryManagerType
* Move FlushUboDirty into UpdateState.
* Buffer dirty cache, rather than ubo cache
Much cleaner, may be reusable for Inline2Memory updates.
* This doesn't return anything anymore.

* Re-add App Exit disposes in proper order
nit: switch case spacing

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
* Implement Modding Support
* Executables: Rewrite to use contiguous mem and Spans
* Reorder ExeFs, Npdm, ControlData and SaveData calls
After discussion with gdkchan, it was decided it's best to call
LoadExeFs after all other loads are done as it starts the guest process.

Layered FS approach has considerable latency when building the final
romfs. So, we manually replace files in a single romfs instance.

* Typo
* Implement Jump Table for Native Calls
NOTE: this slows down rejit considerably! Not recommended to be used
without codegen optimisation or AOT.
- Does not work on Linux
- A32 needs an additional commit.
* A32 Support
(WIP)
* Actually write Direct Call pointers to the table
That would help.
* Direct Calls: Rather than returning to the translator, attempt to keep within the native stack frame.
A return to the translator can still happen, but only by exceptionally
bubbling up to it.
Also:
- Always translate lowCq as a function. Faster interop with the direct
jumps, and this will be useful in future if we want to do speculative
translation.
- Tail Call Detection: after the decoding stage, detect if we do a tail
call, and avoid translating into it. Detected if a jump is made to an
address outwith the contiguous sequence of blocks surrounding the entry
point. The goal is to reduce code touched by jit and rejit.
* A32 Support
* Use smaller max function size for lowCq, fix exceptional returns
When a return has an unexpected value and there is no code block
following this one, we now return the value rather than continuing.
* CompareAndSwap (buggy)
* Ensure CompareAndSwap does not get optimized away.
* Use CompareAndSwap to make the dynamic table thread safe.
* Tail call for linux, throw on too many arguments.
* Combine CompareAndSwap 128 and 32/64.
They emit different IR instructions since their PreAllocator behaviour
is different, but now they just have one function on EmitterContext.
* Fix issues separating from optimisations.
* Use a stub to find and execute missing functions.
This allows us to skip doing many runtime comparisons and branches, and reduces the amount of code we need to emit significantly.
For the indirect call table, this stub also does the work of moving in the highCq address to the table when one is found.
* Make Jump Tables and Jit Cache dynmically resize
Reserve virtual memory, commit as needed.
* Move TailCallRemover to its own class.
* Multithreaded Translation (based on heuristic)
A poor one, at that. Need to get core count for a better one, which
means a lot of OS specific garbage.
* Better priority management for background threads.
* Bound core limit a bit more
Past a certain point the load is not paralellizable and starts stealing from the main thread. Likely due to GC, memory, heap allocation thread contention. Reduce by one core til optimisations come to improve the situation.
* Fix memory management on linux.
* Temporary solution to some sync problems.
This will make sure threads exit correctly, most of the time. There is a potential race where setting the sync counter to 0 does nothing (counter stays at what it was before, thread could take too long to exit), but we need to find a better way to do this anyways. Synchronization frequency has been tightened as we never enter blockwise segments of code. Essentially this means, check every x functions or loop iterations, before lowcq blocks existed and were worth just as much. Ideally it should be done in a better way, since functions can be anywhere from 1 to 5000 instructions. (maybe based on host timer, or an interrupt flag from a scheduler thread)
* Address feedback minus CompareAndSwap change.
* Use default ReservedRegion granularity.
* Merge CompareAndSwap with its V128 variant.
* We already got the source, no need to do it again.
* Make sure all background translation threads exit.
* Fix CompareAndSwap128
Detection criteria was a bit scuffed.
* Address Comments.
