plugins: add new base object, store display in there. Introduce a new GstVaapiPluginBase object that will contain all common data structures and perform all common tasks. First step is to have a single place to hold VA displays. While we are at it, also make sure to store and subsequently release the appropriate debug category for the subclasses.
