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. https://bugzilla.gnome.org/show_bug.cgi?id=743847
