Keep track of cpuset change requests in ResourceManagerService,
and request changing of cpuset via SchedulingPolicyService.
Bug: 72841545
Test:
1)Using modified Youtube/Exoplayer (that uses softMediaCodec
to decode VP9 profile2), manually verify the following:
- media.codec is put into top-app cpuset playing VP9 1080p HDR
- media.codec is put back into foreground after done
- media.codec stays in foreground cpuset playing other content
- kill the app process, verify media.codec is put back to
foreground until new instances request top-app
- kill mediaserver process, verify media.codec is put back to
foreground until new instances request top-app
- kill media.codec process, starting playback again, verify new
media.codec's cpuset can be changed correctly
- kill system_server process (using 'adb shell stop &&
adb shell start'), verify media.codec is put back to
foreground. Restart playback and verify the cpuset can be
changed correctly.
2) CTS post submit tests

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.

Test: check priority match between audioflinger's and hal's threads
- Move SchedulingPolicyService from audioservice to mediautils
- When starting up a high speed stream config, set request queue thread
to SCHED_FIFO using SchedulingPolicyService
