- Use AtomicInterface to implement device-specific atomic operations.
- Remove DeviceAdapterAtomicArrayImplementations.
- Extend supported atomic types to include unsigned 32/64-bit ints.
- Add a static_assert to check that AtomicArray type is supported.
- Add documentation for AtomicArrayExecutionObject, including a CAS
example.
- Add a `T Get(idx)` method to AtomicArrayExecutionObject that does
an atomic load, and update existing CAS usage to use this instead
of `Add(idx, 0)`.

Replace code such as `myArray.GetPortalControl().Get(0)` with
`vtkm::cont::ArrayGetValue(0, myArray)`, which will just retrieve
the single value without transferring the entire contents of
`myArray` to the host. This should prevent memory thrashing.
Also did some general style clean-ups and fixed loops that called
`GetPortalControl` in the loop body.

This allows for developers to do things such as the following
as constexpr's:
```cxx
constexpr vtkm::Id2 dims(16,16);
constexpr vtkm::Float64 dx = vtkm::Float64(4.0 * vtkm::Pi()) / vtkm::Float64(dims[0] - 1);

The contour worklet test was experiencing normals that were set to NaN
due to problems with computing the gradient of the original field. It
was determined that the problem was caused by the clip filter creating
degenerate cells because the clip plane exactly intersected the points
of the mesh. Although a problem, we found that this behavior also exists
in existing tools like ParaView and VisIt. Thus, it sounds like a
problem to be pushed off to a later day. Instead, just move the plane a
little bit to get it into general position.
Now that Threshold automatically converts its output to CellSetExplicit,
this option is no longer necessary (and the previous implementation did
not work correctly).

This was causing issues for downstream users of VTK-m as it exposed
a bug in CM ( cmake#17952 ) where it was evaluating against the set of
enabled languages instead of possible languages.

Perhaps a better title for this change would be "Make the Threshold
filter not totally useless."
A long standing issue with the Threshold filter is that its output
CellSet was stored in a CellSetPermutation. This made Threshold hyper-
efficient because it required hardly any data movement to implement.
However, the problem was that any other unit that had to use the CellSet
failed. To have VTK-m handle that output correctly in other filters and
writers, they all would have to check for the existance of
CellSetPermutation. And CellSetPermutation is templated on the CellSet
type it is permuting, so all units would have to compile special cases
for all these combinations. This is not likely to be feasible in any
static solution.
The simple solution, implemented here, is to deep copy the cells to a
CellSetExplicit, which is a known type that is already used everywhere
in VTK-m. The solution is a bit disappointing since it requires more
memory and time to build. But it is on par with solutions in other
libraries (like VTK). And it really does not matter how efficient the
old solution was if it was useless.
