Date format mapper - redo

Description

This is a redo from an earlier PR: #5676
With this PR you can set your own formats when using date fields.

Text from prev PR:

The relates issue noted that using {@post_date} always displays the mysql format (Y-m-d h:i).
This PR sets this to the default formatting settings from WordPress.

This PR also adds a format param to the magic tag: {@post_date._format.Y-m-d}, {@post_date._format.Y m d} and even {@post_date._format.Y.m.d} (note the dots).
Currently this PR only supports this for core-field dates (post_date). But might be a cool feature for other date fields as well.

Would like to have feedback/ideas on how to best implement this.

This PR does NOT change the default behavior. It only adds the option to define a format (or select WP default format).

Looks good to me, we could improve with some assertions on an object field but it's good either way

There's a test failure on the first assertion at https://github.com/pods-framework/pods/pull/7041/files#diff-2c2cd009a6ec8c79443141f820e785b79db4f0d63491de1d5a2bf0d978f271fbR620

I do not get why the tests are failing, and definitely not why it returns false.
When I test the field locally it works, only the tests (also locally) are failing.
