audio: Implement transient state testing

Browse Source 
Add ModuleDebug.streamTransientStateDelayMs parameter to ensure
that streams stay in transient states for the specified amount of
time. This enabled sending commands from VTS while the stream is
still in a transient state.

Add 'getStatus' stream command to retrieve current positions,
counters, and stream state. Previously we were planning to use a
zero-sized burst command for that, however, after the
introduction of stream state machines, the 'burst' command is
not handled in every stream state, and may even affect the
current state, thus it's no more usable for this purpose.
