[TASK] FormEngine: Allow for selective processing of TCA columns

Add providers that take care of selecting the columns that need to be
processed for the given form data group. This allows removing all
columns not explicitly required by a prior provider (or manually filling
the list), streamlining the amount of work that needs to be done.
