Define GIDs for internal media file types.
Currently, all internal media storage files (under /data/media) are
given the same "media_rw" GID. To support an upcoming optimization
to disk usage calculation, this CL defines three new GIDs that can be
used to quickly identify common types: audio, video, and images.
