910988b9 - [AMDGPU] Stop treating AMDGPU_CS_ChainPreserve as a module entry funtion (#183718)

[AMDGPU] Stop treating AMDGPU_CS_ChainPreserve as a module entry funtion (#183718) Starting with AMD PAL metadata v3.6, pipeline ELFs cannot have a `.shader_functions` section. However, dynamic VGPR retry helpers use the `AMDGPU_CS_ChainPreserve` calling convention, which LLVM previously treated as a module entrypoint, incorrectly emitting this metadata.
