[libclc] Split off library build system into helpers
This splits off several key parts of the build system into utility methods. This will be used in upcoming patches to help provide additional sets of target-specific builtin libraries. Running llvm-diff on the resulting LLVM bytecode binaries, and regular diff on SPIR-V binaries, shows no differences before and after this patch.
