  -----------
  AMDGPU: Fix not diagnosing unaligned VGPRs for vsrc operands (#155104)

This was not checking the alignment requirement for 64-bit
operands which accept inline immediates. Not all custom operand
types were handled in the switch, so round out with explicit
handling of all enum values, and change the default to use
the default checks for unhandled cases.

Fixes #155095
