xwayland: Try the Xwayland glamor hook to create pixmaps

When creating the window buffer's backing pixmap, try the Xwayland
glamor hook first and fallback to the regular CreatePixmap() code path
otherwise.

That allows to enable direct scanout if possible, either through the
regular dmabuf v4 code path, or from the implicit fallback code path.
