TSan reports a data race between writing at cpp:1162 and reading at
h:262. Make the thread_state atomic to prevent this.

a2731424a6 hle: kernel: KThread: Improve Increment/Decrement RunningThreadCount. 
- Previously implementation was incorrect, and would occasionally underflow.

b3f8d2491d hle: kernel: KThread: Ensure host (dummy) threads block on locking. 
- But do not enter the priority queue, as otherwise they will be scheduled.
- Allows dummy threads to use guest synchronization primitives.

247a7e2205 hle: kernel: KThread: Ensure dummy threads never call EndWait. 
- These are only used by host threads for locking and will never have a wait_queue.

cc4cbff1ca hle: kernel: KThread: Rename thread_type_for_debugging -> thread_type.

b52516263d core: hle: kernel: KThread: Integrate with KWorkerTask and implement DoWorkerTaskImpl. 
- This is used to terminate a thread asynchronously after it has been exited.
- This fixes a crash that can occur in Pokemon Sword/Shield because a thread is incorrectly closed on svcExitThread, then, the thread is destroyed on svcCloseHandle while it is still scheduled.
- Instead, we now wait for the thread to no longer be scheduled on all cores before destroying it from KWorkerTaskManager, which is accurate to HOS behavior.

914431487b core: hle: kernel: KThread: Replace Suspend with UpdateState & various updates.

b12695ddc4 core: hle: kernel: Implement thread pinning. 
- We largely had the mechanics in place for thread pinning, this change hooks these up.
- Validated with tests https://github.com/Atmosphere-NX/Atmosphere/blob/master/tests/TestSvc/source/test_thread_pinning.cpp.

bc45d0fc1a core: hle: kernel: KThread: X18 should be a cryptographically random number. 
- This was added with firmware 11.0.0 (https://switchbrew.org/wiki/11.0.0).
    - X18 is OR'd by kernel with 1, to make sure it is odd.
