Use the `MapFieldPermutation` function when mapping point coordinates
for points that are removed. (This function was already being used for
the rest of the fields.) Also remove some unneeded code in the
`CleanGrid` worklets.
There is a limitation in Windows builds using VS2019 where libraries cannot be
bigger than 4GiB. This is normally not an issue but in `VTKm` due to its strong
template usage libraries can reach that size.
The `VTKm` filter library is can easily reach that size and it will halt the
build
This MR tries to avoid reaching those sizes for now by splitting the filter
library into four smaller libraries.
The proposal scheme is:
It splits vtkm-filter into:
- vtkm-common, Classes that are dependencies of other filter libs.
- vtkm-contour, Contour class and its instantiations.
- vtkm-contour, Gradient class and its instantiations.
- vtkm-extra, Classes other than Contour or Gradient that are
not dependencies.

According to talks with Rob Maynard, using a worklet should be
(counterintuitively) faster than using ArrayHandlePermutation with
ArrayCopy.
This change also gives an opportunity to handle invalid indices, which
may be intentionally set when no mapping is available for that value.
For this case, MapFieldPermutation now takes an invalidValue argument to
set such values.
This function is compiled into the vtkm_filter library, so all filters
can implement this type of mapping without providing their own version
of compiling it.
Because we only compile it once, we provide more types to convert.
Hopefully the total compile time balances out.
