[AMDGPU] Restructure code object metadata creation
- Rename runtime metadata -> code object metadata
- Make metadata not flow
- Switch enums to use ScalarEnumerationTraits
- Cleanup and move AMDGPUCodeObjectMetadata.h to AMDGPU/MCTargetDesc
- Introduce in-memory representation for attributes
- Code object metadata streamer
- Create metadata for isa and printf during EmitStartOfAsmFile
- Create metadata for kernel during EmitFunctionBodyStart
- Finalize and emit metadata to .note during EmitEndOfAsmFile
- Other minor improvements/bug fixes
