Wayland: Use tags to verify proxy ownership

Browse Source 
This is in preparation for adding support for libdecor, which creates
its own proxies on our display.  It will likely also be helpful to some
people using native access on Wayland.

This is partly based on the implementation of libdecor support in
PR #1693 by @ christianrauch.
