The geofencing client defines methods for (un)registering and getting a list of
registered regions. By plumbing these through WebFrame, the client will only be
available for Document contexts, and thus not for Worker contexts.

Given that the primary power of Geofencing can be found in workers, this doesn't
make sense. Instead, these calls should go through the Platform class, which
isn't related to any specific Frame/View.
