adaptive_cloth: Mesh: compute info for newly added elements

Using MeshDiff which provides the newly added elements, iterate over
these elements and calculate certain required information. This makes
it easier to take care of things. If there is a MeshDiff produced,
always call compute_info() with it. This ensures all required
information is always available.
