tdf#141341 docxexport: consolidate conversion of NumTypes

so that one comprehensive function is used for Page and Footnote
numbering types (which was already being used by list numbering).

I also added support for CHARS_ARABIC_ABJAD <=> arabicAbjad,
which was my trigger for consolidating all this.

OOXML has one definition (ST_NumberFormat) that specifies the valid
values for pgNumType, numFmt (list numbering),
numFmt (Endnote and Footnote numbering), so use the same
conversion function for all of these.
[Also used for caption, but I haven't noticed that yet in export.)

In the previous code, there was no possibility for
fmt.isEmpty() [despite repeated checks for that situation].
However, I thought it made sense to not specify anything if
the conversion didn't match something known (because perhaps
the locale could take over then?). In any case, that is a
slight change, but for pgNumType we were specifying "none"
instead of decimal, which didn't make much sense either.
So I don't expect anyone crying 'regression' over that.
