# Description

Cache PhysX view's DOF paths before looping when processing fixed
articulation tendons to improve loading time.

For the Shadow Hand task, calling `self.root_physx_view.dof_paths` when
iterating over all joints to find tendons attached (in
`Articulation._process_fixed_tendons` method) is an "expensive"
operation. Timing can be reduced from 2.2 seconds to 300 milliseconds
(13th Gen Intel® Core™ i9-13950HX × 32, RTX 5000) by calling
`self.root_physx_view.dof_paths` once
