Add call recording tone support.

Adding carrier configuration option to specify whether the carrier requires
the incall recording tone be played.
Added phone account extra used in Telephony to communicate this to
Telecom.
Added permission pregrant for Telecom for MODIFY_AUDIO_ROUTING; this is
needed as Telecom listening to the AudioRecordingConfiguration callback
from the audio framework.  It needs the permission so that it can be
informed of the package names of recording apps.

Test: Manually enabled for local carrier and confirmed that recording
tone plays to remote party when a recording app is started on the device.
Bug: 64138141
