Temporarily restore device identifiers access to Profile Owner

Temporarily restore access to device identifiers for a profile owner on
a personal (non corporate-owned) device.

This is a partial revert of ag/9845617.

As this change breaks some Corp use cases, we will be working with the
affected parties on a timeline to re-introduce it.
