Make Mapplauncherd support optional

It's worth revisiting if this makes sense to keep as a dependency with
some repeatable benchmarks where a quantifiable difference may or may
not be observed when running this on a watch.

If this is to be removed cmake/FindMapplauncherd_qt*.cmake additionally
should also be gone.
