* 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
