[DO NOT MERGE] Grant all access_media_location permission

Test: Manual testing:
         All combinations of
           - App targetSdk = 28 and 29 (and 22 for extra credit)
           - App having the <uses-permission> tag for
             ACCESS_MEDIA_LOCATION or not
           - Upgrade from P->Q-QPR and from vanilla Q->Q-QPR
         Further upgrade of targetSdk from 28->29 while on Q-QPR
         ==> All permission behavior should make sense. Sometimes there
             are weird, but expected behaviors. Hence we need to
             collect the results and then look at the unexpected ones.
             See SplitPermissionTest for some tests I added for the
             location-background permission which was split from
             the fine/coarse-location permissions
