[TASK] Cleanup ReferenceIndex class

* Since introduction of class ReferenceIndexUpdater each
  record is handled only once when updating the reference
  index. The record runtime cache is obsolete and can be
  dropped.

* The $excludedTables and $excludedColumns properties are
  non-static now: In normal operation only one instance
  of ReferenceIndex class is created and used for many
  records, there is no point in creating hard to evict
  static state.

* A runtime cache has been used for information derived
  from TCA (no db calls). This is dropped in favor of a
  class property.
