[Paraview] Calculator disabled when no point or cell data exists in ParaView 3.98.0

[Cory Quammen]

In ParaView 3.14.1, I used to be able to create quick test data sets
by using the Point Source and applying the Calculator filter to it to
generate some point data using the coordinates of the points in the
point source.

This is no longer possible in 3.98.0. Is that by design? I'd argue
that the calculator should be available in this case. A perhaps more
common use case would be using the Calculator to perform a
transformation on point coordinates in an object.

Thanks,
Cory
