wayland: Set EGL swap interval to 0.

Browse Source 
There's no need for EGL to do any timing, we do it in GTK already.

This fixes hangs in Mesa when we hide a surface after a SwapBuffers()
but before the frame callback arrives.
If we then reshow the surface and immediately render to it, Mesa would
still have a frame callback from before the hiding and forever poll()
waiting for the compositor to send the callback.

Fixes #5761
