DateFormats: Default ISO & US formats should be consistent and not change if current date is today (#27300)

* DateFormats: Default iso / US formats should be consistent and not change if current date is today

* rename and updated tests

* Updated changelog

CHANGELOG.md

+# 7.2.0-beta1 (unreleased)
+
+### Breaking changes
+
+* **Units**: The date time units `YYYY-MM-DD HH:mm:ss` and `MM/DD/YYYY h:mm:ss a` have been renamed to `Datetime ISO`
+ and `Datetime US` respectively. This is no breaking change just a visual name change (the unit id is unchanged). The
+ unit behavior is different however, it no longer hides the date part if the date is today. If you want this old
+ behavior you need to change unit to `Datetime ISO (No date if today)` or  `Datetime US (No date if today)`.
