[AMDGPU] calling conventions for AMDPAL OS type Summary: This commit adds comments on how the AMDPAL OS type overloads the existing AMDGPU_ calling conventions used by Mesa, and adds a couple of new ones.

[AMDGPU] implemented pal metadata Summary: For the amdpal OS type: We write an AMDGPU_PAL_METADATA record in the .note section in the ELF (or as an assembler directive). It contains key=value pairs of 32 bit ints. It is a merge of metadata from codegen of the shaders, and metadata provided by the frontend as _amdgpu_pal_metadata IR metadata. Where both sources have a key=value with the same key, the two values are ORed together. This .note record is part of the amdpal ABI and will be documented in docs/AMDGPUUsage.rst in a future commit. Eventually the amdpal OS type will stop generating the .AMDGPU.config section once the frontend has safely moved over to using the .note records above instead of .AMDGPU.config.

; amdpal pixel shader: check for 0x2c0a (SPI_SHADER_PGM_RSRC1_PS) in pal
; metadata. Check for 0x2c0b (SPI_SHADER_PGM_RSRC2_PS) in pal metadata, and
; it has a value starting 0x42 as it is set to 0x42000000 in the metadata
; below. Also check that key 0x10000000 value 0x12345678 is propagated.
