wp-date is deprecating its moment method, so we need to localize

Closes #4533 and #9109

How has this been tested?

@nosolosw and @jasmussen would you mind looking to see if the capitalization rules are correct in Español and Dansk? It's correct for English but I'm seeing lower-case where I'm not expecting it.

To test, check out the branch, set your language in wp-admin, then open the "Publish" date picker on a post. All the changes are in PHP so no rebuild is needed.

For core merge we might do something similar as with wp_localize_jquery_ui_datepicker()

In Spanish, Month and Day of Week are in lowercase, both in the settings page and the date picker.

Settings page:

If I choose "j M, Y" in the date format input, I see the textual three letters month in uppercase (eg: Nov), but the calendar still shows the full month.

I've checked and different apps have different ways to localize dates in Spanish: I get lowercase months in some and uppercase in others.

In case it's helpful, I've checked the Spanish translations in GlotPress (WordPress project) and they are consistent with what I saw in the settings page/calendar (lowercase for weekdays and whole months, uppercase for 3-letter months):



This does work for me in French and Arabic. I'd have preferred a fix in the data picker component instead of relying on moment being available as a global. That said it can be refactored later.

Would you mind rebasing and merging?
