ryan schmidt be36fdfeb2 ModelingTools: fix issues w/ bad mesh changes being created in dynamic mesh sculpting. ...

Problem is that during remesh passes the affected triangle set can expand (due to splits/collapses on ROI boundary) and our tracking of it is not perfect. Remesher now tells ChangeTracker before it modifies an edge, rather than Sculpt tool trying to predict set of modified triangles up front.

In theory this allows for smaller changes, because often only a subset of triangles are modified. However ChangeTracker currently only emits modified vertices as part of modified triangles. So we still need to save the full triangle ROI. Made several MeshChangeTracker functions protected for now, because they cannot be used externally due to this limitation. Updated call sites to those functions (which were likely also buggy).
