wayland: Remove EGL-dependent code.

This removes all EGL-specific code from the wayland backend.

Notable unresolved question: due to wayland design, the resizing
methods will only get/set the size of the drawn borders, not of the
actual content drawn. This latter size cannot be controlled by winit.
