feat: add Field::displayIf method

[zorn-v]

Allow display fields based on other fields values of entity, for example

Field::new('field_one')->displayIf(static fn ($entity) => $entity->getFieldTwo() > 0)

Currently it only possible via form extension in FormEvents::PRE_SET_DATA form builder event listener, which not so convinient.

Closes #6102
