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

aaudio: indicate client UID and PID to audio flinger
Implement correct indication of client UID and PID to audio flinger
for AAudio MMAP streams in both exclusive mode and shared mode.
- Add start/stop client methods on MMAP streams used only when the MMAP
stream is in AAudio service and carries a mix of shared streams.
- Add "In Service'" indication from "client" side to AAudioServiceStreamMMAP
so that the behavior can be adapted accordingly.
- Modify logic on audio flinger side with regard to mmap tracks and
audio HAL stream activity:
- use same audio session for all clients on a same stream to match
audio policy logic to share same direct output stream for clients on same
session. This is also more consistent with current volume and effect
handling as all MMAP clients sharing the same output stream have the
same volume and use case.
- start/stop the HAL when the stream is started/stopped with the initial client
handle (returned when the stream is opened) but do not create a track.
AAudioService implementation will always send an additional start command before
first client starts and a stop command after last client stops,
in both shared and exclusive mode.
- start/stop a track only if the start/stop stream command is received
with a handle different from the initial handle.
- Allow more than one active client from the same UID on a MMAP input in audio policy.

audioflinger: define MMAP HAL Stream control interface
Added definition of MmapStreamInterface used by Oboe service
to open, configure and control MMAP streams at the audio HAl.
This interface is implemented by audioflinger and abstracts the details
of interacting with audio policy manager and audio HAL from Oboe service.
A callback interface MmapStreamCallback is also defiend to communicate
volume and routing changes back to Oboe service.

Test: build
