surfaceflinger and apps are clients of Configstore HAL
This commit marks surfaceflinger and app domain (except isolated_app)
as clients of Configstore HAL. This cleans up the policy and will make
it easier to restrict access to HwBinder services later.
Test: Play YouTube clip in YouTube app and YouTube web page in Chrome
Test: Take an HDR+ photo, a normal photo, a video, and slow motion
video in Google Camera app. Check that photos show up fine and
that videos play back with sound.
Test: Play movie using Google Play Movies
Test: Google Maps app displays the Android's correct location
