tdf#129961 svx: add rendering for table shadow as direct format

There was already shadow support in
ViewContactOfTableObj::createViewIndependentPrimitive2DSequence(), but
the UNO API and UI could only set the shadow properties on a shape
style, so shadow-as-direct-format is new.

One difference between the PowerPoint shadow and our shadow is that we
draw shadow for table text as well, while PowerPoint only does it for
the borders / cell fill style.

This means we're either backwards-compatible or compatible with
PowerPoint. Solve this problem by leaving the style case unchanged, but
render direct formatting like PowerPoint.
