VVLTC parameters tweak

Some notes:

  • Both tests were conducted on top of reduce full depth search twice #5848.
  • Based on tuning suggestions, the extension for capturing the previously moved piece was removed/simplified. (Developers can attempt to reintroduce it post-merge if needed.)
  • Initially, bonusScale = std::max(bonusScale, -2); was included but later removed in the second test upon Viz's request, however, it was nearly non-functional anyway.
