wayland: Bind Wayland EGL display ourselves

Browse Source 
This will allow us less awkward startup, where previously we had to
pre-initialize Wayland very early so Cogl could bind the Wayland display
when it initialized. Move things around so we bind the Wayland EGL
display when initializing the rest of Wayland infrastructure.
