[PATCH 1/7] winewayland.drv: Respect the compositor requested surface config.

[Alexandros Frantzis]

From: Alexandros Frantzis

If we are processing a config request by the compositor, consider that
config as authoritative for the window. Otherwise use the window state
to determine the new Wayland state to apply.
