Sam Haves 2e13c64308 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.
