DATA is deprecated, but some apps really want it.

The DATA column points at raw filesystem locations, which aren't
always valid when an app is placed into a sandbox, so apps need to
move away from using them.

We had hoped to block this access based on an app targeting Q, but
we've received feedback that it's too painful for apps to transition,
so we'll continue returning paths that can be translated.

Also reduce CPU usage by skipping permission checks when not
processing an IPC, such as when called by ModernMediaScanner.
