[Feature] Add vtkMassProperties (volume/surface area calculation)

[vishnusureshperumbavoor]

Motivation

Currently, vtk.js does not provide an equivalent to VTK’s vtkMassProperties class, which is essential for calculating mesh volume, surface area and shape index.

Detailed Description

I would like vtk.js to support mesh analysis features similar to VTK’s vtkMassProperties, including:

• Volume calculation for closed triangle meshes
• Surface area computation
• Normalized shape index

This would enable browser-based applications to perform geometric analysis without server-side computation.

Potential alternatives (currently unavailable) include manually porting the C++ algorithm to JavaScript, but this is non-trivial and error-prone.

I think it might be relevant to start looking at vtk.wasm for which we have a webinar in 2 days.
