AudioService: log stream mute events

Mute events are logged separately from volume events as
those happen more often and would cause older mute events
to roll off the logging window
Log an error when trying to unmute a stream that should
stay muted due to the set of muted streams by ringer and
zen mode.

Also invert muting and updating mask of muted streams
so the state always precedes the update of the stream,
in order to identify incorrect mute state changes.

Test: adb shell dumpsys audio | grep -A 30 "mute commands"
