aaudio: fix timestamps and underruns
Start the client after we get valid timing data from the server.
That can take a while because of the long cold start times.
The client is synced with the current position of the service.
Now the client can start clean with no underruns.
Bug: 63918065
Test: test_timestamps.cpp

aaudio: fix EXCLUSIVE mode interfering with SHARED
The MMAP endpoints were not tracked by the EndpointManager
so it could not broker EXCLUSIVE access. To fix this the MMAP stream
was refactored to use a per-client stream and a per-device endpoint.
Cleanup close() of MMAP stream.
Add AAudioServiceEndpointShared.cpp.
Extract AAudioServiceEndpointMMAP from AAudioServiceStreamMMAP.
Track MMAP endpoints so we can manage EXCLUSIVE and SHARED access.
Bug: 64494572
Bug: 64310586
Test: see bug, use write_sine to play a shared stream and a excl stream
