The newer version of `ArrayHandle` no longer supports different types of
portals for different devices. Thus, the `ReadPortalType` and
`WritePortalType` are sufficient for all types of portals across all
devices.
This significantly simplifies supporting execution objects on devices,
and thus this change also includes many changes to various execution
objects to remove their dependence on the device adapter tag.
This fixes a bug introduced in commit
93d87e06fd7a0ef479a324e5cd2453c1c7ece0ee
Part of the commit moved fromusing a `BoundaryState` object to keeping
boundary flags in a `vtkm::Vec<bool,3>`. However, the meaning of the
flag got inverted. The `BoundaryState::IsRadiusIn?Boundary` methods
returned true if the current location was inside the bounds (i.e. _not_
on the boundary), but the new flags are true if the current location is
on the boundary (the inverse).
The updating of the code for the `StructuredPointGradient::Jacobian`
method got the flag somewhat wrong and scaled the wrong case.
This commit splits ThreadIndicesTopologyMap into two
different specializations which can be instanciated with the
tags: DefaultScatterAndMaskTag and CustomScatterAndMaskTag.
These specialization will allow ThreadIndicesTopologyMap
instances to avoid holding in memory InputIndex, OutputIndex and ThreadIndex
variables when Mask = MaskNone and Scatter = ScatterIdentity which in this case
are not needed since no transformation are done.

This change is needed for being able to use different thread indices types
without changing Fetchs. Basically decoupling those two areas.
1. This commit removes concrete specialization instantiations of
ThreadIndicesTypes in all of the Fetch's specializations.
2. It also moves the ThreadIndicesType template parameter from the Fetch
struct to a template parameter in their methods Load/Store.

This is a flag that functions in the execution environment can return to
report on the status of the operation. This way they can report an error
without forcing the entire invocation to shut down.
The old version of ExecutionObject (that only takes a device) is still
supported, but you will get a deprecated warning if that is what is
defined.
Supporing this also included sending vtkm::cont::Token through the
vtkm::cont::arg::Transport mechanism, which was a change that propogated
through a lot of code.
The `From` and `To` nomenclature for topology mapping has been confusing for
both users and developers, especially at lower levels where the intention of
mapping attributes from one element to another is easily conflated with the
concept of mapping indices (which maps in the exact opposite direction).
These identifiers have been renamed to `VisitTopology` and `IncidentTopology`
to clarify the direction of the mapping. The order in which these template
parameters are specified for `WorkletMapTopology` have also been reversed,
since eventually there may be more than one `IncidentTopology`, and having
`IncidentTopology` at the end will allow us to replace it with a variadic
template parameter pack in the future.
Other implementation details supporting these worklets, include `Fetch` tags,
`Connectivity` classes, and methods on the various `CellSet` classes (such as
`PrepareForInput` have also reversed their template arguments. These will need
to be cautiously updated.
The convenience implementations of `WorkletMapTopology` have been renamed for
clarity as follows:
```
WorkletMapPointToCell --> WorkletVisitCellsWithPoints
WorkletMapCellToPoint --> WorkletVisitPointsWithCells
```
The `ControlSignature` tags have been renamed as follows:
```
FieldInTo --> FieldInVisit
FieldInFrom --> FieldInMap
FromCount --> IncidentElementCount
FromIndices --> IncidentElementIndices
```
Mask objects allow you to specify which output values should be
generated when a worklet is run. That is, the Mask allows you to skip
the invocation of a worklet for any number of outputs.
Did a bit of renaming of the support classes used for
WorkletPointNeighborhood. First, the OnBoundary tag is changed to
Boundary to match other tags and reflect some changes in the resulting
methods. Also moved the BoundaryState and Neighborhood classes from
vtkm::exec::arg to vtkm::exec to be more accessible. Finally, the
Neighborhood class name was changed to FieldNeighborhood to be more
specific on what role this class plays with neighborhood.
Previously, WorkletPointNeighborhood had a template argument to select
the size of the neighborhood. This change removes that template
argument. Instead, the vtkm::exec::arg::BoundaryState methods now take
in a size parameter when determining when it overlaps the boundary.
If in the future we want to add the ability to select the neighborhood
size at compile-time (for performance reasons), I suggest adding this
template argument to the OnBoundary tag for ExecutionSignature.
Rather than force all dispatchers to be templated on a device adapter,
instead use a TryExecute internally within the invoke to select a device
adapter.
Because this removes the need to declare a device when invoking a
worklet, this commit also removes the need to declare a device in
several other areas of the code.
While making changes to how execution objects work, we had agreed to
name the base object ExecutionObjectBase instead of its original name of
ExecutionObjectFactoryBase. Somehow that change did not make it through.
In order to make the change from the current way execution obejcts are utilized to the new proposed executionObjectFactory process type checks now has to look for the new execution object factory class to check against.

accordingly.
VTK expects that the tensor fields generated by the gradient of a vector field
to have FORTRAN ordering instead of C ordering.
Discovering this actually uncovered bugs in the Vorticity and QCriterion
implementation where they presumed FORTRAN ordering, and would generate
incorrect results.
Basically we can run the gradient worklet and compute the Divergence, Vorticity,
and QCriterion without ever having to store the gradient tensor in global memory
