[gnome-maps] ContextMenu: Add 'I am here!' menu item

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit 69af8b3951d2e7af8ab04ecde050c421a58e72b6

    ContextMenu: Add 'I am here!' menu item
    
    When launched, it overrides Maps's concept of user location. We also do
    a reverse geocoding to set a proper name on the user location pin.
