Warn if non-permitted keyword arguments are given to compiler methods

This can help future generations avoid mistakes like this:
https://github.com/xkbcommon/libxkbcommon/commit/edb1c662394578a54b7bbed231d918925e5d8150

To avoid breaking builds, this is currently just an error. After
sufficient time has passed this can hopefully become a hard error,
similarly to the already-existing `permittedKwargs` warnings.
