kernel: Implement thread pinning support (#2840)
* kernel: Implement Thread pinning support
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
