Always get raw keyboard layout on macOS

Some input sources are still using input methods even though they
claim to be "ASCII" input. This causes our input handling to fail
since we need to query the layout to handle dead keys.

Fortunately there is another API to get the raw, underlying input
source that the input method uses. So let's use that and be sure
that we're always getting something we can use.
