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.

fbab3dc017 hle: kernel: Fix service_threads access to be thread safe V2. 
- PR #7699 attempted to fix CreateServiceThread and ReleaseServiceThread to be thread safe, but inadvertently introduced a possible dead-lock.
- With this PR, we use a worker thread to manage the service thread list, allowing it only to be accessed by a single thread, and guaranteeing threads will not destroy themselves.
- Fixes a rare crash in Pokemon Sword/Shield, I've now run this game for ~12 hours non-stop and am quite confident this is a good solution for this issue.

ef9186172f hle: kernel: Fix service_threads access to be thread safe. 
- CreateServiceThread and ReleaseServiceThread can be accessed by different threads, uses a lock to make this thread safe.
- Fixes a rare crash in Pokemon Sword/Shield that can occur when a new service thread is being created while an old one is being destroyed.

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).

5192e8e092 core: hle: Remove global HLE lock. 
- This was added early on as a hack to protect against some concurrency issues.
- It's not clear that this serves any purpose anymore, and if it does, individual components should be fixed rather than using a global recursive mutex.
