Fix and improve functor cache

• Handle gracefully non-split or special 0x8xxx TCKs
• Set output file when creating TCK functor cache
• Support generating functor cache from settings for non-split mode
• Add tests where python functors or functor cache is forced.
  Unfortunately, the functors depend on EnableOutputStreaming and outputFile, so the cache won't catch all functors and when one runs without these options being set, python functors are needed.
• Fix LBHLT-281
