Add ability to set supported audio routes on phone accounts and connection

The set audio routes are used by Telecom to restrict where the audio may
be routed to. For example, an account can specify that calls may not be
routed over bluetooth headsets, which will prevent a new call from being
routed to this source.

This is a cherry-pick of abandoned ag/1521009.
