Update Arrangement2d's triangulation functions to use that fill mode, and also to be explicit about whether the boundary group is expected or not

also fix handling of splitting into connected components when some of the components don't have a valid convex hull (by bailing on the component split in that case)

Works by trying a bunch of plane cuts to break reduce the volume of the convex pieces, then merging them back together to remove those that were not helpful. We need the merge step especially for meshes where it takes multiple plane cuts to start reducing the hull volumes, as the initial cuts in that case are not informed by the error metric.

- fix bug with detection of vertices on the solid segment of a ghost triangle
- detect when 'fill' of a triangulation is ambiguous under winding rules (e.g. due to open edges)
- optionally automatically track duplicate vertices and remap duplicate-vertex references to the vertex that was actually inserted

[CL 19521151 by Jimmy Andrews in ue5-main branch]
- Report failures to constrain edges, optionally detecting the case where the edge was flipped away by a subsequent constraint (happens if the constraint edges intersect)
- Add options to directly triangulation TPolygon2 and TGeneralPolygon2 (+ the supporting fill algorithms to be run on any array of edges)
- Add validation of Delaunay property for CDTs on all non-constrained edges
- Update edge cache (if enabled) on sub-triangulation append, improving perf on CDTs with many constrained edges
add corresponding test coverage, and change the test runner to always automatically run exact predicates globalinit

- Support InCircle
- Support float as well as double
- Add safer, templated versions that specify whether float or double is to be used (for TVector/TVector2)
