use possessive genitive case month names in number formatter

* Switching between noun and genitive case month names is very simply done:
* If the format contains a day of month (D or DD) code, genitive case is used.
* If there is no day of month, the month noun is used. For example for
a standalone MMMM code or a combined MMMM-YYYY code.
* For input both, noun and genitive case, forms are recognized.
