Add MuteableAudioOutputStream interface to export SetMute().

This CL is part of enabling (E)AC3 passthrough feature.
Will create AudioTrack output stream to handle compressed bitstream
formats, so AudioManagerAndroid should not dependent on the additional
function of OpenSLESOutputStream. Instead, create a new interface,
MuteableAudioOutputStream, to export the additional function,
SetMute().
