Add e_pixmap API for testing if a pixmap is a native surface

DMAbuf for wayland will complicate determining whether a pixmap can use
a native surface or not, so we add an API here to check this.

Note that this doesn't take compositor capabilities into account - for
example, X pixmaps need GL enabled to use native surfaces.  This is
already tested elsewhere.
