12f636d4 - Revert "[libclc][CMake] Use clang/llvm-ar on Windows (#186726)" (#191745)

Revert "[libclc][CMake] Use clang/llvm-ar on Windows (#186726)" (#191745) This reverts commit 4abb927bacf37f18f6359a41639a6d1b3bffffb5. The code is not needed since 121f5a96ff38 because the C compiler is now always just-built clang in in-tree build. In addition, CMAKE_AR is llvm-ar and CMAKE_RANLIB is llvm-ranlib.
