Replace QtMultimedia usage with 4A + gstreamer

Replace QtMultimedia usage for ringtone playing with a gstreamer
pipeline that uses the provided 4A role ALSA device for output.
For now, a "phone" role is assumed to be available, but it does
not exist in the current set of 4A policy and HALs, and needs to
be added.  Testing was done by making the required role changes
locally and using some debug QML tweaks to allow triggering the
ringtone manually.
