This included two fixes.
1) a bug that would choose the average position when collapsing an edge on a mesh boundary ( so not retaining a vertex location )
2) eliminates the chance that an edge adjacent to a UV seam (or other attribute seam) will collapse to the vertex not on the seam (this would have moved the seam and resulted in new attribute values).

Additionally this CL:
Introduces a simplifier-level bool allow for easy switching between simplification with and without quadric memory and adds logic to remove isolated triangles
Extend MeshOverlay to identify seam-end edges - DynamicMeshAttributeSet.{h,cpp} DynamicMeshOverlay.{h,cpp}
Expose ability to recompute edge constraints - MeshConstraintUtil.{h,cpp} MeshConstraints.h

ModelingTools: Expose Simplify To Minimal Planar simplification mode in Simplify Tool. Add edge filter to this simplification mode in TMeshSimplification. Add support for returning all edges along intersection curves in FMeshBoolean and FMeshSelfUnion. Add option BooleanMeshesOp and SelfUnionMeshesOp to apply minimal-planar simplification along these cut/intersection edges. Expose as toggles in CSGMeshesTool and SelfUnionMeshesTool
