ARMeilleure: Move TPIDR_EL0 and TPIDRRO_EL0 to NativeContext (#4661)

* ARMeilleure: Move TPIDR_EL0 and TPIDRRO_EL0 to NativeContext

Some games access these system registers several tens of thousands of times in a second from many different threads. While this isn't really crippling, it is a lot of wasted time spent in a reverse pinvoke transition.

Example games are Pokemon Scarlet/Violet and BOTW. These games have a lot of different potential bottlenecks so it's unlikely you will see a consistent improvement, but it definitely disappears from the cpu profile.

* Remove unreachable code.

* Add ulong conversion for offsets

* Nit
