wayland: Add roundtrip in SetWindowFullscreen() to get new size 

The video core assumes that window->w/h will be updated before returning
from SetWindowFullscreen(). This is needed to generate a resize event
with the correct window size when exiting fullscreen.

The roundtrip allows us to receive the configure callback that informs
us of the new window size before returning.

Fixes #6043
