Simplify parsing from USD stage to kinematic tree for mjSpec population.
...
Summary of changes:
- Move stage parsing from usd_to_mjspec to kinematic_tree
- A Node now has lists of paths for prims that we support parsing.
- When parsing the stage, we create a list of all the Nodes that we will place in our tree.
- Removed the need for expensive SdfPath maps and sorting of bodies in favor of indexed integer arrays.
- Simplifies usd_to_mjspec parsing as we can process each node and it's owned prims one at a time.
