xwayland: populate window_properties in json for views

window_properties is documented to contain a subset of the X11 properties
of a window (its title, class, instance, role, and transient ID). This
commit adds the missing json object from the get_tree output for
xwayland windows only.

This is a follow-up of #2911.
