Date column ui component locale date format

[Karlasa]

Description (*)

added option to fallback to locale date format configuration.
So in case lets say in ui component xml you pass empty value you can automatically fallback to locale date format.

Fixed Issues (if relevant)

Fixes issue where ui component have hardcoded date format and when having multi site with different date formats it adds option to fallback to locale settings.
example: Have this issue with requisition lists grid in B2B in storefront.

Manual testing scenarios (*)

By default it doesn't change anything but if you change passed settings in component level and send empty value you can use locale specific settings.

Hi @Karlasa. Thank you for your contribution. Would you provide a little bit more information about the use case:

Fixes issue where ui component have hardcoded date format and when having multi site with different date formats it adds option to fallback to locale settings.

So, if an UI component has a hardcoded date format, the following check https://github.com/magento/magento2/pull/22213/files#diff-8c266c07ae31f60348f20567f5fa5d92R29
does not override the hardcoded value. So a value from locale won't count.

Thank you.

@rogyar
I will use it with patch where I remove UI component setting value (as it's not possible to remove under theme)
example like this:

Just figured that it would be good to have this option if anyone will be going to create something new with those components :)
