tdf#134646 Remove "nearest paper matching" feature

This was introduced with da62b0feb684b34ab191fb0f03ed5432c14cba97 to find
the best paper size for user defined page sizes.

However, this leads to problems with Impress: Slides have screen sizes which
have no relation to paper sizes. For the slide site "Screen (16:9)" the
page size "Executive" is the nearest matching size.

However, this paper is (though supported by printers), very uncommon.
We do not want the nearest matching paper size the printer supports, but
rather we want to fit the slide on the printer default paper.

Note that finding a matching print paper still works (and it even has some
fuzzy matching), so some sort of "nearest paper matching" still exists,
(but with sane limits).
