vtkSelectPolyData: Array name support for selection scalars
requested to merge HollowSun/vtk:#18614-vtkSelectPolyData-selection-scalars-missing-array-name into master
The point of this MR is to control the selection scalars array name from the outside.
Also, this fixes issue #18614 (closed) because it wouldn't add the array to the output because it was undefined.
Fixes issue #18616 (closed)
Fixes issue #18617 (closed)
