[libclc] [libclc][CMake] Add COMPONENT ${ARG_PARENT_TARGET} to install (PR #182716)

[Wenju He via cfe-commits]

https://github.com/wenju-he created https://github.com/llvm/llvm-project/pull/182716

Toolchain can specify the component to explicitly install libclc to a deploy folder. E.g. our downstream SYCL toolchain deploy: https://github.com/intel/llvm/blob/e7b423fd517d/sycl/CMakeLists.txt#L531

Also check ARG_PARENT_TARGET is defined and non-empty.
