Fix for Ticket #311 Scaling List Bugs

• Wrong scaling list sizes used.
  • Scaling factor incorrect for dependent quantization.
  • 32-bit variable overflow in dependent quantization.
  • Transform skip only applies to luma.
  • Pred matrix ID delta adjusted for non-existent 2x2 luma lists.

As an proponent, we provide other solutions for those bugs in !601 (merged)
