Malcolm Nixon 5b8b2a4e70 Add ability to drive full-body avatars using OpenXRHand
This PR allows the OpenXRHand to drive:
- OpenXR rigged hand skeletons located under the OpenXRHand node
- Godot Humanoid rigged hand skeletons located under the OpenXRHand node
- OpenXR rigged avatar skeletons located separately in the scene-tree
- Godot Humanoid avatar skeletons located separately in the scene-tree
