Bug 1885831 [Wayland] Skip EGL window size changes and disable rendering of it if compositor is paused after scale change r=emilio

Browse source 
Skip rendering of EGL window right after scale changes. MESA backend contains old back / front buffers and we need to recreate them for new scale at ResumeCompositorFlickering().
