Revert "[libc++] Build GoogleBenchmark directly from Lit" (#225620)

Reverts llvm/llvm-project#224192

The original PR introduce implict dependency on cmake from path. Further
more, the cmake invocation from googlebenchmark.py didn't inherit
CMAKE_MAKE_PROGRAM and cmake generator flags from the parent LLVM build,
causing implicit dependency on make. It causes test failures on systems
that do not have these installed or config in their default path.
