  [CMake] Use LLVM tools external project build where possible

This reduces the reliance on host tools and makes the build more
hermetic. Some of the runtimes already assume that certain tools are
always available, for example libc++ and libc++abi archive merging
relies on ar to extract files out of the archive, even on Darwin.
