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.
Because ArrayPortalSOA calls a delegate portal to get the actual values,
it can only implement its own Set or Get if the delegate portal supports
it. Previously this was done by calling an overloaded internal method
based on the result of PortalSupportsSets/Gets. However, regardless of
whether the delegate portal supported Set or Get, ArrayPortalSOA
provided one. Thus, if something else tried to use PortalSupportsSets/
Gets on ArrayPortalSOA, it would always report true even if it was not
really supported.
Instead, use SFINAE to remove the Set or Get if that method is not
supported in the delegate portal.
Since ArrayHandleSOA is only really used for portals from basic storage
arrays, it will be rare that Set or Get is not supported. However, a
device adapter is free to remove one of these methods on a device
portal. For example, if you call PrepareForInput on an ArrayHandle, it
is possible that the device adapter will create a portal that has no Set
method because the array is not writable.
Thanks to Allison Vacanti for recomending this solution.
I kept getting warnings from different compilers about type conversions
because I was making values by adding an index to them. Change how we
create and test values so that these type issues are less likely to come
up.
Apparently, the Visual Studio 2015 has a bug where the result of a
decltype might not be considered a type. Attempt to get around this
problem by putting the decltype inside of a struct and then have the
using statement use the typename keyword. Hopefully if you literally say
that something is a typename, the compiler will treat it like a type
name.

The gradient is malformed at the apex of a pyramid. To get around this,
steal a trick from the VTK source where in this case interpolate some
values a little bit into the interior of the cell.
Also expand the gradient worklet tests to include all cell types.
