vtkMeshQuality: Adding partial support for non linear cells

The filter now has an optional flag `LinearApproximation`, which, if
turned on, computes cell quality for non-linear cells, which are treated
as if they were linear. This computation is dumped into a second output
array.

In addition, unsupported cell types now output NaN, so the user can know
when no quantity has been computed.
