video: wayland: Handle 0x0 xdg_toplevel_configure in fullscreen

The xdg_shell spec seems to state[1] that xdg_toplevel_configure events can
always provide a 0×0 width/height to signal that the compositor doesn't
care. SDL previously assumed the provided width/height was always valid
for fullscreen windows, and so applied it as-is.

This broke SDL applications on KDE/KWin 5.23, which now sends 0×0
configure events (and, in 5.23.3, 1×1 events for some reason), breaking
all SDL applications in fullscreen[2].
