AMDGPU/GlobalISel: Add regbanklegalize rules for load and store (#153176) 
Cover all the missing cases and add very detailed tests for each rule.
In summary:
- Flat and Scratch, addrspace(0) and addrspace(5), loads are always
  divergent.
- Global and Constant, addrspace(1) and addrspace(4), have real uniform
  loads, s_load, but require additional checks for align and flags in mmo.
  For not natural align or not uniform mmo do uniform-in-vgpr lowering.
- Private, addrspace(3), only has instructions for divergent load, for
  uniform do uniform-in-vgpr lowering.
- Store rules are simplified using Ptr32 and Ptr64.
  All operands need to be vgpr.

Some tests have code size regression since they use more sgpr instructions,
marked with FixMe comment to get back to later.
