cxxmodules: support new round of Clang patches

These patches now support the `-MF` output, so remove the `none` support
added just for the old patchset which did not use it.

Also update the flag name to `-fmodule-output=`.

Due to the new Clang module mapper flag, use a new experimental support
UUID as well.
