Introduce IStreamCallback interface for non-blocking I/O. Add 2 new stream states: TRANSFERRING and TRANSFER_PAUSED, and define state machines for the async case. Add DrainMode as in previous HAL versions. Note that non-blocking input is not fully implemented because it did not exist in previous HAL versions, and the corresponding AudioInputFlag does not exist yet. Enhance VTS state machine tests to allow waiting for an async event. Bug: 205884982 Test: atest VtsHalAudioCoreTargetTest Change-Id: I0a18a6d930dee5941f769e08083817d41ff941e6
