Treat AML as a "partial grant" for apps that support photo picker

When an app supports the photo picker permission prompt (by targeting T+
and explicitly requesting READ_MEDIA_VISUAL_USER_SELECTED), then treat
the ACCESS_MEDIA_LOCATION permission as a "partial grant", given when
clicking "select photos" or "allow all", and not silently expanding if
READ_MEDIA_IMAGES/VIDEO are requested later
