sw table cell borders: add optional Word-compatible border collapsing

We always compared border width and other aspects only after that, Word
works with border weight according to their implementer notes.

So extend svx::frame::Style to be able to collapse borders using weights
and opt in for that from sw/ in case a compat mode (which is related to
tables, off by default and is set by the DOC/DOCX import) is set.
