GstVaapiMiniObject and GstVaapiObject are deprecated.
This is the first step to remove them by porting GstVaapiSurface as
a GstMiniBuffer descendant.

Adds a new function that changes the internal EGL display to the
current one (eglGetCurrentDisplay()) and sets the current context
too (eglGetCurrentContext()).
This new function is called by gst_vaapi_texture_egl_create() updating
the GstVaapiDisplayEGL with the current EGL display.

It is required to use the context of the calling thread when wrapping
a foreign texture. According the documentation of
GstVideoGLTextureUploadMeta:
"The caller of gst_video_gl_texture_upload_meta_upload() must
have OpenGL set up and call this from a thread where it is valid
to upload something to an OpenGL texture."
This patch updates the EGL display and context in GstVaapiDisplay
instance to the one used by te renderer that uploads the texture.

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.

Add GstVaapiTextureEGL abstraction that can create its own GL texture,
or import a foreign allocated one, while still allowing updates from a
VA surface.
