tdf#101710 Fix invalid style:data-style-name attribute

There were two problems with this attribute:

1. It was written in style:table-cell-properties instead of
in style:style.

2. It was referencing a number format id, instead of a style
name. Moreover, the data style wasn't even exported as part
of office:styles (if at all).

Both import and export were affected. For export, it was easily
possible to reuse some related stuff from Calc, so that stuff
was moved into xmloff and used from there (there are no logic
changes for Calc). For import, loading of the invalid attribute
was kept for compat reasons. Although it's only useful for
automatic number formats, as the data styles weren't exported
properly anyway (e.g. see the document attached in bugzilla).
