Make sure to clean up :focus-visible as well as :focus for shadow hosts.

This is supposed to be cleaned up by the datetime widget in:

  https://searchfox.org/mozilla-central/rev/188d0f76a73e0671d12e744a71e9f5701668cc37/toolkit/content/widgets/datetimebox.js#600,623

But that may never happen if we tear down the widget before via a type
change, and we don't quite want to unconditionally unfocus when tearing
down (we might want to close the picker, but that's a separate issue).

Make sure to always unset :focus-visible as well from shadow roots to
fix it, and add exhaustive tests.
