wayland: Only dispatch frame events in Wayland_GLES_SwapWindow

Browse source 
Dispatching all events in Wayland_GLES_SwapWindow leads to resizes being
acked before the program has a chance to handle the resize. This change
reduces jumping on fullscreen transition with apps that call
SDL_PollEvent before issuing any render calls.
