Updates the mergeFromVert and mergeToVert vectors in order to create a
manifold solid. If the MeshGL is already manifold, no change will occur and
the function will return false. Otherwise, this will merge verts along open
edges within tolerance (the maximum of the MeshGL tolerance and the
baseline bounding-box tolerance), keeping any from the existing merge
vectors.
There is no guarantee the result will be manifold - this is a best-effort
helper function designed primarily to aid in the case where a manifold
multi-material MeshGL was produced, but its merge vectors were lost due to
a round-trip through a file format. Constructing a Manifold from the result
will report a Status if it is not manifold.
