AIMF should have its own set of state enums

case in point: AudioInputDevice(which impls AIMF::Delegate) has TODOs for
kAudioStreamPaused saying it should be Stopped and a NOTIMPLEMENTED() for
kAudioStreamPlaying since playing doesn't make sense for input (perhaps it
should be capture or even better removed entirely if it's not used?)

Makes sense.  I'll make interface definitions for input in the ipc header file
under media/audio.
