Include an AppOp to allow dialer role app to record and play audio into calls

This change includes an AppOp that will be used to grant access to telephony call audio (RX and TX) to the default dialer application (assigned to the Dialer role).
A new permission was created so only apps that also require this permission will be granted. It will also be used to keep track of usage (audit).
