[TASK] Streamline extbase data / column mapping

The extbase data and column mapping is now properly
using the TCA schema API. While streamlining the
code some divergences regarding relation handling
have been observed (e.g. use of "maxitems" and
"renderType" options). Those will be tackled
separately, since streamlining this might be
breaking.
