vtkDataSetSurfaceFilter: improve alg for structured grid.

Utkarsh Ayachit requested to merge utkarsh.ayachit/vtk:perf-extract-surface into master

Avoid unnecessary heavy template include in header. Not only could this be avoided by restructuring the code but also avoid include bloat. vtkDataSetSurfaceFilter.h is included in several places.

Use a different algorithm for computing surface for structured grids with blanking. The new algorithm is about 10 times faster in fast mode and 4 time faster in non-fast mode in my debug build for a 100^3 image data. The new algorithm does not require accessing each input cell in fast mode and hence the speedup.

Also making vtkDataSetSurfaceFilter::Delegate work for structured grids i.e use vtkGeometryFilter internally, if requested.

Addresses paraview/paraview#20885 (closed)

Found a bug in vtkGeometryFilter, which has been reported here: #18279 (closed)
