AudioService: fix missing CEC message on unmute after vol down
Group in one method sending volume / mute updates to HDMI CEC
when applicable. Use this method, maybeSendSystemAudioStatusCommand,
to avoid code duplication.
Add missing synchronization in onUnmuteStream for stream mute check.
When STREAM_MUSIC is unmuted, also call
maybeSendSystemAudioStatusCommand for a mute adjust, to ensure
other CEC devices' UI is in sync with the internal state.
Bug: 136977965
Test: with ATV device in system audio mode, mute with remote, then \
press vol down on TV remote, verify TV display matches ATV UI \
with current volume.
