Reintroduce avatar forearm IK
Avatar IK currently only rotates the Hand joint, which looks a bit weird in some cases. HiFi apparently used to support this, but they disabled it and the issue that change resolved was on their now-dead issue tracker.
To repeat the information from https://github.com/vircadia/vircadia-native-core/issues/452 : Apparently it's better explained than I remember it: https://github.com/overte-org/overte/commit/3fa3cd8cfdb9be2ec3f4d1c160e000a35c9cceb8 There is a somewhat large High Fidelity PR which I believe never got merged: HiFi_PR_15341.zip "This pr enables the elbow pole vector to compensate for the orientation of the hand so that we can avoid painful wrist contortions."
