[!!!][TASK] TCA: Remove wizard _HIDDENFIELD and hideParent

The functionality provided by _HIDDENFIELD and hideParent on TCA
wizard level can be better realized with the new renderType
registration provided by the NodeFactory. A search showed that
not a single TER extension used the two options, and it is probably
also used very rarely in other 3rd party extensions. It is dropped
now without substitution.
