tdf#125591 DOC import: lazy-load metafiles with explicit size

Regression from commit 69b62cfcbd364d7f62142149c2f690104b217ca1
(tdf#125281 DOC import: fix size of lazy-loaded metafiles, 2019-05-27),
the problem is that setting the preferred size of a Graphic swaps it in.

Avoid this by extending ImportUnloadedGraphic(): if a size hint is
provided, then that will be used instead of info from the graphic
descriptor (which is usually only meaningful for bitmaps).

This way we maintain the correct size and we're back to lazy-loading
metafiles from binary MSO files as well.
