feat(filter.date): add support for default datetime formats in en

- add support for full,long, medium, short datetime formats in en

Breaks MMMMM. now we don't support MMMMM anymore as old implementation differs
from Unicode Locale Data format we are following.

- removed support for fullDateTime and fullTime as it means too much
trouble with full timeZone names
- added docs for the new features
