Request cpuset change for 1080p HDR using soft decoder

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
