tdf#70838 ww8export: rotate shape vertically = swap width/height

During import, rotation past 45 degrees swaps height and width
in SvxMSDffManager::ImportShape, so exporting needs to do the same.

restored from abandonment and corrected by Justin

Import also adjusts TopLeft position, but position seems to
generally be set by other factors on export. Prefer to have
an example proof document and not just guess since it seems
that position is affected by many factors. Therefore, not
doing anything about the position in this commit.
