Threshold was producing wrong results with options `SetAllInRange(false)` and
`SetComponentToTestToAll` because the logic of running
`worklet::Threshold::RunIncremental` on individual components of the input
field and combining the results is incorrect for this case.
With this fix, component modes 'Any' and 'All' are handled by applying
the threshold criteria to each component of each value of the field,
combining the results, and running the threshold worklet on the result
array.
In reflection, the `WarpScalar` filter is surprisingly a superset of the
`WarpVector` features. `WarpScalar` has the ability to displace in the
directions of the mesh normals. In VTK, there is a distinction of normals
to vectors, but in VTK-m it is a matter of selecting the correct one. As
such, it makes little sense to have two separate implementations for the
same operation. The filters have been combined and the interface names have
been generalized for general warping (e.g., "normal" or "vector" becomes
"direction").
In addition to consolidating the implementation, the `Warp` filter
implementation has been updated to use the modern features of VTK-m's
filter base classes. In particular, when the `Warp` filters were originally
implemented, the filter base classes did not support more than one active
scalar field, so filters like `Warp` had to manage multiple fields
themselves. The `FilterField` base class now allows specifying multiple,
indexed active fields, and the updated implementation uses this to manage
the input vectors and scalars.
The `Warp` filters have also been updated to directly support constant
vectors and scalars, which is common for `WarpScalar` and `WarpVector`,
respectively. Previously, to implement a constant field, you had to add a
field containing an `ArrayHandleConstant`. This is still supported, but an
easier method of just selecting constant vectors or scalars makes this
easier.
Internally, the implementation now uses tricks with extracting array
components to support many different array types (including
`ArrayHandleConstant`. This allows it to simultaneously interact with
coordinates, directions, and scalars without creating too many template
instances.

The `AmrArrays` filter generates some cell fields that specify information
about the hierarchy, which are constant across all cells in a partition.
These were previously stored as an array with the same value throughout.
Now, the field is stored as an `ArrayHandleConstant`, which does not
require any real storage. Recent changes to VTK-m allow code to extract the
array as a component efficiently without knowing the storage type.

Previously, Clip was updated to remove unused points from the input.
This requires a re-mapping of point ids after compaction. This
re-mapping was missed for the points used for interpolation of centorid
points.
The flying edges algorithm (used when contouring uniform structured cell
sets) was not interpolating cell fields correctly. There was an indexing
issue where a shortcut in the stepping was not incrementing the cell index.
There was a bug in `CleanGrid` when removing degenerate polygons where it
would not detect if the first and last point were the same. This has been
fixed.
There was also an error with function overloading that was causing 0D and
3D cells to enter the wrong computation for degenerate cells. This has also
been fixed.

Previously, the MIR filter ran a check the dimensionality of the cells in
its input data set to make sure they conformed to the algorithm. The only
real reason this was necessary is because the `MeshQuality` filter can only
check the size of either area or volume, and it has to know which one to
check. However, the `CellMeasures` filter can compute the sizes of all
types of cells simultaneously (as well as more cell types). By using this
filter, the MIR filter can skip the cell type checks and support more mesh
types.

The `GhostCellRemove` filter had some methods inconsistent with the naming
convention elsewhere in VTK-m. The class itself was also in need of some
updated documentation. Both of these issues have been fixed.
Additionally, there were some conditions that could lead to unexpected
behavior. For example, if the filter was asked to remove only ghost cells
and a cell was both a ghost cell and blank, it would not be removed. This
has been updated to be more consistent with expectations.
The original intent of calling the `Statistics` filter on a
`PartitionedDataSet` was that the resulting `PartitionedDataSet` would
have partitions matching the input giving the statics of each partition
(as well as the overall statistics in global fields). There is a comment
in the code that says as much.
However, the partitioned version of `Execute` deleted the statistics.
This corrects the behavior by leaving in the partitions' statistics.
This is also now being tested.
