LOG: [libclc] Suppress AMDGCN code object version for library code (#174412)

Summary:
The code object version defines the ABI the HSA executables follow. This
prevents it from hard-coding it in the OpenCL libraries and preventing
users from overriding it when using them.

Added: 
    

Modified: 
    libclc/CMakeLists.txt
