Create configuration for fields to exclude from ReferenceIndex
The patch https://review.typo3.org/#/c/35191 moves the fields formerly hardcoded in getRelations() to a class member to improve performance.
Christian Kuhn and Frans Saris would like to have a configurable solution instead.
When implementing this: Beware a new instance of ReferenceIndex is currently being instanciated for each record! So a configurable solution must provide these fields very fast, best might be to introduce a cache too.

In #79387 - https://review.typo3.org/#/c/51362/11/typo3/sysext/core/Classes/Database/ReferenceIndex.php we removed the TODO.
Defining columns which are excluded from the reference index in ALL tables of an installation does no longer seem to be a good idea:
Patches to the core always can easily extend/change that column list, extensions should not.
In general it might be an idea to define certain fields inside a specific table to be excluded, but I currently see no use case.
For now I think its sufficient on table level. Should this topic arise again reopen this issue.
