libaudiohal: When starting write, consider the stream buffer size
When starting writing into a stream, use the bigger value from
the requested bytes to write and the stream buffer size.
This fixes a corner case when offload playback starts close
to the end of the track, and then jumps to the middle.
Bug: 63979005
Test: checked HAL logs for the repro case,
confirmed that Loopback, PM, YT, Camcoder, still work, also over BT

audioflinger: Adjust priority of hal threads
HALs are prohibited from using framework binder, and there is
no equivalent scheduling policy service in hwbinder. Thus, in order
to match priorities of FastCapture / Mixer threads with their
counterparts in the HAL, it is needed to request the priority boost
from audioflinger on behalf of the HAL.
Test done to verify the priority was correctly set.

audiohal: Make sure audio data transfer related commands go via FMQ
When outputting audio, the framework issues several HAL calls
from the same thread that writes into data FMQ. These calls
also need to be served on the same thread that writes audio data
to HAL. The same thing happens when audio input is commenced.
Add a command FMQ for passing different commands to the HAL thread.
This way, depending on the calling thread, the same call may go
either via hwbinder or via the command queue.
This dramatically reduces jitter in RTT measurements (although
doesn't improve the latency).

Test: scripted RTT app

Update StreamHalHidl to use IStreamOut.WriteStatus new field
Updated the client code to use the new field:
IStreamOut.WriteStatus.presentationPositionRetval for providing
legacy-compatible results when calling 'get_presentation_position'
immediately after 'write'.
Bug: 30222631
Test: Loopback RTT, media CTS

libaudiohal: Implement simple HIDL client
This client requires both HIDL client and server to be of the same
ABI version (e.g. 32-bit).
EffectHalHidl::process and EffectHalHidl::processReverse are stubs.
Some extra warnings are logged due to unimplemented functions
in the legacy HAL.
