  [AMDGPU] New RegBankSelect: Handle all 32/64 bit pointer types for B32/B64 rule (#142560)

The previous system explicitly enumerated the types. P0 was missing and thus we couldn't handle a select of P0s for example.
Generalize the logic to simply check the width of the pointer for 32/64 bit pointers, this should handle all common address spaces
