Update to Parry 0.18 (#770)

* update to parry ~main

* use traverse_depth_first

* add example to test intersection

* rely on upstream PR rather than local

* re-enable profiler_ui for examples

* rely on official parry repository

* chore: switch back to the published version of parry

* chore: update changelog

* chore: remove dead code

* fix compilation of rapier3d-meshloader and rapier3d-urdf

* chore: cargo fmt

@@ -19,6 +19,7 @@
 - `InteractionGroups` default value for `memberships` is now `GROUP_1` (#706)
 - `ImpulseJointSet::get_mut` has a new parameter `wake_up: bool`, to wake up connected bodies.
 - Removed unmaintained `instant` in favor of `web-time`. This effectively removes the `wasm-bindgen` transitive dependency as it's no longer needed.
+- Significantly improve performances of `QueryPipeline::intersection_with_shape`.
