Add a 'source ID' concept to the convex part decomposition, to enable tracking of which hulls were not merged to any other hulls when running the convex hull merging algorithm.

Note: These settings were all introduced post-5.3, so moving them should not require deprecation

1. A MaxHullVertices setting. If positive, the convex hull algorithm will greedily add vertices to best expand the hull, generating a simplified hull if the exact hull would exceed the specified budget.
2. SkipAtHullDistanceAbsolute/SkipAtHullDistanceAsFraction settings. If positive, the convex hull algorithm will ignore points that are closer than the threshold value, resulting in a simpler hull.
Also stop relying on the Orient3 exact predicate to find the farthest hull points (regardless of whether PointsBudget is specified) both so that the PointsBudget and SkipAtHullDistance settings can accurately compare distances from different triangles and also to fix an issue where the Orient3 magnitude was discarded when requesting a single-precision Orient3 value.
Update convex hull unit test to also test these new settings.
Also adds a small optimization the reduces the number of duplicate points considered.

Add initial PointSetFunctions to Geometry Script, including: K-Means Clustering, Flatten/Unflatten, Make Bounding Box, Transforms -> Points
Add a custom For Each-style macro to provide a more convenient interface for working with the clustering result

Specifically the computations of attribute gradients now uses a local coordinate system defined in terms of the triangle faces.
