LOG: [libclc] Make sure PACKAGE_VERSION is set for libclc (#193966)

Summary:
This can be unset because CMake does not expose this as a raw variable
when you use the find_package interface. If it is not set as in the case
of standalone builds the clang resource directory won't be found

Added: 
    

Modified: 
    libclc/CMakeLists.txt

Removed:
