ecore-evas-wayland: Use engine 'hidden' field for ecore_evas_hide operations

This patch allows us to set a 'hidden' flag in the Evas Engine
information structure instead of setting a NULL surface. Setting this
flag allows us to hide/show a canvas without having to
destroy/recreate a wl_surface every time.
