Hyunjun Ko 185da3d1a4 libs: display: GstVaapiDisplay as GstObject descendant
This patch is to change the inheritance of GstVaapiDisplay to GstObject,
instead of GstVaapiMiniObject. In this way we can use all the available
infrastructure for GObject/GstObject such as GstTracer, GIR, etc.

In addition, a new debug category for GstVaapiDisplay is created to make it
easier to trace debug messages. It is named "vaapidisplay" and it transverse
all the VA display backends (DRM, GLX, EGL, Wayland, ...)

This patch is a step forward to expose GstVaapiDisplay for users in a future
library.
