UnusedBonesByReferencesTool #

Marks it as EditorOnly that bones referenced only from EditorOnly meshes.

This component should be added to an avatar root. (Kind: Avatar Global Component)

This component is obsolete. You should use `Remove unused Objects` of [Trace and Optimize](../trace-and-optimize) instead. This component will never get algorithm improvements.

This is port of UnusedBonesByReferencesTool by Narazaka but run at build time.
