sw, numbering portion format: consider full-para char formats as well

The bugdoc had a single paragraph with direct formatting (24pt font
size), numbering enabled and a bookmark covering half of the paragraph.
The numbering had default font size, not inheriting from the paragraph.

Turns out that in case the bookmark is removed, then the custom font
size is not an autoformat set on the whole text of the paragraph but
rather a format on the paragraph level, which does influence the
formatting of the numbering portion, as expected.

Fix the problem by extending SwTextFormatter::NewNumberPortion(), so it
looks for char props not only in the item set of the SwTextNode, but
also in the hints of SwTextNode, if they cover the whole paragraph. This
fixes the inconsistency that adding a bookmark to the document should
not change the rendering of the portions.

Interestingly DOCX import already set the font size on the SwTextNode in
this case, but the ODT import created a char autofmt hint, that covered
the full paragraph.
