Gwenole Beauchesne f5af9d150e window: add toplevel display indirection for visualid and colormap.
Add GstVaapiDisplay::get_{visual_id,colormap}() helpers to help determine
the best suitable window visual id and colormap. This is an indirection in
view to supporting EGL and custom/generic replacements.
