ad53dc22fd hle: kernel: KServerSession: Simplify CompleteSyncRequest EndWait. 
- Considering is_thread_waiting is never set, so we can remove IsThreadWaiting.
- KThread::EndWait will take the scheduler lock, so we can remove the redundant lock.

f499c8177e 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.

cc112f971e 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.

2147240e47 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.

c73841500a 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.
