XPU: temporary fix for NVidia driver issue for >= 531.18 drivers

Renamed the Point Cloud Reconstruct SOP to Point Cloud Surface.

The Merge LOP parameter dialog is now clearer about when it will respect the Strip Layers parameter. There should be no change in behavior.

Fixed the Worley noise VOP implementation of of Chebyshev metric. It was incorrectly using the Manhattan metric.

Fixed a crash that happens in the animation graph editor when deleting all keys in a channel while draw past ends is on.

Fixed hou.Parm.multiParmInstancesCount() and hou.Parm.multiParmInstancesPerItem() to act the same as hou.Parm.multiParmInstances() with regards to separator parameters and tuple parameters. Separator parameters can't return a valid hou.Parm, so were skipped by hou.Parm.multiParmInstances() when returning the hou.Parm list. Tuple parameters are returned as individual hou.Parm by hou.Parm.multiParmInstances(). This was leading to a mismatch in parameter count returned by a len(hou.multiParmInstances()) and hou.Parm.multiParmInstancesCount() and there was no easy way to get the real number of parameters per items.

Fixed the RMB node menu to always show the Dirty This Node option for TOP nodes. This fixes the case where there was no easy way to dirty the contents of a Subnet TOP node containing a partially cooked node network.

The USD ROP "Files to Save" parameter now affects the saving of volume files generated by a save operation as well as USD files.

Fixed Houdini crash on startup when the "Load payloads by default in new LOP networks" preference is turned off.

The USD Render ROP now deletes both temporary USD and VDB files post-render, rather than just USD files.

Fixed an issue with the USD Render ROP not working properly when both "Render All Frames With a Single Process" and "Flatten Stage" were set.

"Replace Previous Bake" will now remove all foliage instances when the Foliage Type is specified for an instancer

"Replace Previous Bake" will now remove foliage instances when the Foliage Type is specified for an instancer when baking.

Fix a rare case in the Vellum Solver where simulating very small triangles with Triangle Stretch constraints could lead to NAN values when using the CPU OpenCL driver.

Allow the scene graph tree and collection tree primitive filter patterns to match the Houdini Layer Info primitive.

When the Duplicate LOP creates collections with duplicate names, it now creates the collection with the union of all requested contents, rather then the contents of the "last" request.

Fixed a bug where the crowd solver did not necessarily interpolate the target orientation correctly for motor-driven ragdolls. The 'motor_hastargetprev' attribute was not explicitly set on the constraint network by the solver, so the behaviour relied on the "Use Initial Motor Target" parameter value on the cone twist constraint relationship DOP node in the DOP network.

Mtlx Normal node will no longer output front-facing N so that nodes that take in normal input will behave consistently regardless of whether it's using default geometry normal or have world-space Mtlx Normal wired in.
