When exiting camera app, camera daemon is still busy in background,
which may affect the launch animation of launcher. So, limit the cpuset
of camera daemon to little cores for 1 second when there is app launch
hint to improve it. This only happens when camera is running. Also bypass
this behavior when video recording is active.

Bug: 240889279
Test: camera daemon cpuset changed as expected
