kernel: Implement SetMemoryPermission syscall (#2772)
* kernel: Implement SetMemoryPermission syscall

This commit implement the SetMemoryPermission syscall accurately.
This also fix KMemoryPermission not being an unsigned 32 bits type and
add the "DontCare" bit (used by shared memory, currently unused in
Ryujinx)

* Update MemoryPermission mask

* Address gdkchan's comments

* Fix a nit

* Address gdkchan's comment
