Wayland: Simplify decoration side detection

Browse Source 
This commit simplifies the detection of which element of a fallback
decorated window the pointer has entered.  Instead of looping through
the list of windows, the user pointer of fallback decoration surfaces is
set to the GLFW window object.

(cherry picked from commit cd466cf9fd)
