  wayland: Only dispatch frame events in Wayland_GLES_SwapWindow 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.
