audio: Implement the major functionality of the primary CF HAL
Core HAL changes:
1. Add StreamPrimary implemented via StreamAlsa.
2. Align the configuration with the HIDL HAL.
3. Fix position retrieval vs. standby call.
4. Fix sleeps in StreamAlsa.
VTS changes:
1. Use several bursts for stream I/O test scenarios that check
observable position increase. This is because the position may
not be available until a couple of transfers have been made.
2. Do not require position increase for the scenarios that do
not make several bursts. As specified above, the position may
not have been increased for the ALSA case. Whereas, using
multiple bursts in all scenarios will increase test time, and
make the state machine transitions graph more complicated.
3. Hook up the test config file to shut down audioserver during
VTS tests, fix the test config file.
Bug: 286914845
Test: atest VtsHalAudioCoreTargetTest
Test: compare APM dumps for AIDL vs. HIDL
