  -----------
  [AMDGPU] Add SubtargetFeature for dynamic VGPR mode (#130030)

This represents a hardware mode supported only for wave32 compute
shaders. When enabled, we set the `.dynamic_vgpr_en` field of
`.compute_registers` to true in the PAL metadata.

This will be changed to use an attribute after downstream consumers
have been migrated.
