Arabic language is missing meridiem function

[alandio]

Describe the bug
In all Arabic locales ar-xx there exists a localized meridiem, but only in the basic ar locale this does not exist. For reference here is how it is done in moment.js https://github.com/moment/moment/blob/e96809208c9d1b1bbe22d605e76985770024de42/locale/ar.js#L143-L154

Another issue which is not related to this and might open another issue for it, is that none of the ar-xx locales use Arabic numerals like seen in the figure below. Is this a decision taken by the team?

Expected behavior
The ar locale should also localize meridiem to show 'م' or 'ص'
