Title: feat(dateFilter): Add option to display date as am/pm

This adds a new option in order to choose whether to display a date as
AM/PM or am/pm.

Note: This contains a breaking change. `a` now will display am/pm,
whereas the old behavior is specified by `A` for AM/PM.

This is in support of #8763 .
