Move common VA display creation code to GstVaapiPluginBase, with the default display type remaining "any". Also add a "display-changed" hook so that subclasses could perform additional tasks when/if the VA display changed, due to a new display type request for instance. All plug-ins are updated to cope with the new internal APIs.
