gnome: add to contact

Adds context menu item which allows the user to choose an existing
contact or create a new contact to add the selected contact method
to.

Note: this currently seems to fail with non local address books
(specifically with google contacts), even though the EDS methods
will ocasionally return as having succeeded. This is a bug which
will be addressed in later patches.

Issue: #78234
