Overview Actions - shows a message if action is blocked by policy. 

Device policy or app secure surface policy mean that snapshot based
actions shouldn't work.
This is encoded in whether the snapshot is "real", the fake snapshot is
generated when policy doesn't allow captures.

Test: tested with Test DPC fake device policy app
