Summary: Does something similar to our existing ServerDecoration, but based around XDG Shell patterns and with a few subtle differneces. We'll probably still need both in kwin for the forseeable future as GTK3 won't ever change from using the KDE Server Decoration. Test Plan: Relevant unit test. It's a bit simpler as spec states toolkits must follow what the compositor configures if they bind the interface. Modified plasma-integration to remove ServerIntegration (as Qt5.12 has native support) all my windows look and act the same.
