Refactor VM Settings and add support for voicemail transcription

This CL refactors the existing voicemail settings fragment and adds UI support for voicemail transcription. It mainly deals with the following:
- ensuring that when the VVM toggle is turned off, transcription and donations are gone.
- when transcription is off, donation preference is gone.
- donation is only available when transcription is available and enabled
- as part of the refactor, fixes existing logging bugs
- breaks preferences and its associated methods into helper methods when possible
- groups relevant preferences together when possible
