Fix displacement maps not applied on MaterialX materials in GL viewport

When selecting a work item in the TOPs UI, TOPs will now make sure the global PDG work item is set before sending a HOM event for the selection operation. This makes it possible to access the correct active work item reference through the `pdg.WorkItem()` method.

Fixed incorrect materials shown on curves in SOP context, and attributes not correctly sampled by MaterialX materials on curves, in some cases

Fixed the behavior of the Edit Material Properties LOP in Create Class mode. It now creates a class prim at a particular location without modifying the inheriting material prim at all.

Fixed an issue where ML Regression Train would not work properly on intel-based OSX machines. The fix consists of requiring torch version 2.2.2 instead of 2.4.0. The latter version of torch is not available for these machines.

• Existing recipes can only be overwritten when creating a new one.
• If the edited recipe internal name is changed, delete the original recipe beforesaving the new one.
