fa4f7657 - [AMDGPU] Further improve `AMDGPUSubtargetFeature` multiclass (#177077)

[AMDGPU] Further improve `AMDGPUSubtargetFeature` multiclass (#177077) This PR extends the multiclass to support two additional parameters: one for specifying whether an `AssemblerPredicate` should be generated, and another for dependent `SubtargetFeatures`. This allows 15 more definitions to be converted to use the multiclass.
