Add Intentfilter BasePreferenceController

For settings which can change in the framework, outside of
the settings app and a slice, a Slice needs to be able to
register a listener for these changes.

Adding a getter for an IntentFilter in BasePreferenceControllers
allows us to use the SliceBroadcastRelay in SysUi to listen for
these changes.
