Add support for appcompat preferences rendering

This CL adds new code to handle the support preferences classes. If the
support library is not installed in the project, it will use the regular
inflater as fallback.
This also ports the hotfix that used to live in Android Studio to
support "*Compat" preferences to the regular BridgePreferenceInflater.
