Gwenole Beauchesne 93418ed5ee texture: add generic helper to create textures.
Add new generic helper functions gst_vaapi_texture_new_wrapped()
and gst_vaapi_texture_new() to create a texture without having
the caller to uselessly check for the display type himself. i.e.
internally, there is now a GstVaapiDisplayClass hook to create
textures, and the actual backend implementation fills it in.

This is a simplification in view to supporting EGL.
