Description

As passthrough is the only field not processed for database, it's the only possible TCA type to implement custom information display without adding non existing columns to list view.

Therefore it should be either possible to add custom render types to implement custom renderings for passthrough, or to add a switch to tca type `user` to prevent it from being fetched from database.

Usecase:
We want to add a google map to a record. This map is generated using two additional columns `lat` and `lng`. Also we need to register a new column in TCA to render the map itself, which is not available in database as nothing is stored.
We either can use a new `renderMode` or a TCA column of type `user`.
Both get fetched from database in list view when editor selects the field, which is possible.

It's not possible to select `passthrough` fields in this view. So either there should be a switch for `user` to prevent columns from being processed, or process `passthrough` as usual by node factory, exactly https://github.com/TYPO3/TYPO3.CMS/blob/TYPO3_8-7/typo3/sysext/backend/Classes/Form/Container/SingleFieldContainer.php#L79 .
