tdf#104354 writerfilter: rewrite Autospacing

which also resolves a regression from tdf#113258.

The previous code segments were being spread out all over
the place. It all consolidates nicely in finishParagraph,
and the code is much easier to read using the new
GetAnyProperty function.

Plus there were regressions creeping in.
The mere presense of the Autospacing property normally, but
not necessarily means that it is on. Verify that it is enabled,
and update grabbag if autoSpacing changes.

Additionally, support was added for a zero top margin for
the first paragraph of the document.

This will be too hard to backport since it depends on
150c12fc0fba2c2f4b08b4298678ee49676ebae0 from tdf#72560
and the many code fixes related to GetPropertyFromStyleSheets.
