LOCALE_SGROUPING's string and the `Grouping` field in NUMBERFMTW are confusingly different. The former, which is what is fixed here, treats a '0' as a repeat of the previous grouping. But a 0 at the end of the `Grouping` field prevents it from repeating (it repeats by default otherwise) so it's the opposite. Note that without a '0' in the LOCALE_SGROUPING string, it shouldn't even repeat in the first place.
This fixes the typical "3;0" default grouping, for example.

Fixes a regression introduced by 56099a31242dcc522fb94643e70553e152c522ec.

I found an issue with the Grouping integer field, it did not handle zeros in the middle of the number (or multiple trailing ones) correctly. I've added tests and corrected it now. It has a special case for that, unfortunately, since it's how native works…
