  [AMDGPU][SIMemoryLegalizer] Consider scratch operations as NV=1 if GAS is disabled

- Clarify that `thread-private` MMO flag is still useful.
- If GAS is not enabled (which is the default as of last patch), consider an op as `NV=1` if it's a `scratch_` opcode, or if the MMO is in the private AS.
- Add tests for the new cases.
- Update AMDGPUUsage GFX12.5 memory model
