tdf#103602 xmloff: ODF export: draw:background-size attribute

... on drawing-page style; no import because Writer doesn't have the
property anyway.

It looks like Writer paints color, gradient, hatch and bitmap with
"repeat" on the entire page, and bitmap "scaled" or "no-repeat" within
the borders.
