Adding option to vtkCellSizeFilter to sum cell sizes over the dataset.
Summed cell sizes are returned in field data and this works for composite datasets as well. Also adding an option to make the vtkCellSizeFilter only compute cell sizes for the highest dimension cells in the vtkDataSet so that for composite datasets that desired cell sizes are computed. Also getting rid of some compiler warnings in vtkPUnstructuredGridConnectivity. Addresses paraview/paraview#10433.
