Constraints: add support for a new Owner Local Space for targets.
Add a new transformation space choice for bone constraints, which
represent the local transformation of the bone in the constraint
owner's local space.
The use case for this is transferring the local (i.e. excluding the
effect of parents) transformation of one bone to another one, while
ignoring the difference between their rest pose orientations.
Owner Local Space replaces the following setup:
* A `child` bone of the `target`, rotated the same as `owner` in rest pose.
* A `sibling` bone of the `target`, positioned same as `child` in rest
pose and using Copy Transforms in World Space from `child`.
* The `owner` bone constraint uses Local Space of `sibling`.
(This analogy applies provided both bones use Local Location)
Since the space list is getting long, this adds a couple of separators.
