[TASK] Deprecate TCA sub types

The sub types feature of TCA was used for
registration of plugins as "list_type". Since
it's encouraged to register plugins as CType
since a couple of versions already and the
deprecation of the "list_type" functionality
with #105076 are the sub types now deprecated
as well.

This special functionality just lead to
headaches and should be replaced by using
dedicated record types, making configuration
much cleaner and more comprehensible.
