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

Instead of silently fail to export the image if there is not available
the EGL_MESA_drm_image, log an error message. Also a code refactoring
was done.

Add helpers to import EGLImage objects into VA surfaces. There are
two operational modes: (i) gst_vaapi_surface_new_from_egl_image(),
which allows for implicit conversion from EGLImage to a VA surface
in native video format, and (ii) gst_vaapi_surface_new_with_egl_image(),
which exactly wraps the source EGLImage, typically in RGBA format
with linear storage.
Note: in case of (i), the EGLImage can be disposed right after the
VA surface creation call, unlike in (ii) where the user shall ensure
that the EGLImage is live until the associated VA surface is no longer
needed.
