aaudio: implement sessionId for effects
If a sessionID other than AAUDIO_SESSION_ID_NONE is requested
then legacy data path will be forced.
SessionID is implemented for MMAP data path but not used.
It is easier to implement it now then try to figure
it out later.
Bug: 33268927
Test: test_session_id.cpp will be moved to CTS when stable
