7e894d10a7 [kernel] Correct status for looked up objects 
- The guest will check for 0x40000000 and replace it with
  0xb7 (ERROR_ALREADY_EXISTS), which is the correct return value.
  For example, see:

986dcf4f65 [Base] Check success of sync primitive creation 
- Mainly use `assert`s, since failure is very rare
- Forward failure of `CreateSemaphore` to guests because it is more easy
  to trigger with invalid initial parameters.

052ce3d389 [Kernel] Make KeEnter/LeaveCriticalRegion only affect the caller thread 
Adds a new X_KTHREAD::apc_disable_count field at 0xB0 into X_KTHREAD based on where 360 kernel seems to store it, and made CriticalRegion funcs act on that, instead of locking things between all threads, and changes DeliverAPCs to check that field before running the APCs.

XThread::LockApc/UnlockApc were also updated too as those previously called into EnterCrit/LeaveCrit to work, but AFAIK the code that uses LockApc/UnlockApc does have an actual need for locking between threads, so changed them to work on XThread::global_critical_region_ directly instead.

05ef022fd7 [Kernel] Do not retain handle in ExCreateThread 
Closing the thread handle should delete the thread object
if it's finished. When this handle was retained, closing the handle
left a lingering handle reference and thus this XThread would leak
