The intel compiler could not generate code in a timely manner ( 12+ hours ) when
asked to produce a cross product of very long lists. By moving to a lazy
evaluation scheme we now have all compilers product a cross product in a
reasonable amount of time ( 2-4 seconds ).
This resolves Issues:

If a global static array is declared with VTKM_EXEC_CONSTANT and the code
is compiled by nvcc (for multibackend code) then the array is only accesible
on the GPU. If for some reason a worklet fails on the cuda backend and it is
re-executed on any of the CPU backends, it will continue to fail.
We couldn't find a simple way to declare the array once and have it available
on both CPU and GPU. The approach we are using here is to declare the arrays
as static inside some "Get" function which is marked as VTKM_EXEC_CONT.

Previously we allowed a const ref as we would make a copy, this only works
as it relies on RuntimeDeviceTracker implementing state through a shared_ptr.
Instead if we require modifiable types only we can make TryExecute more
efficient and clearer on what it does.
By using perfect forwarding we can reduce not only the amount of TryExecute
signatures, but we can enable the ability to pass temporary functors to
TryExecute.
At the same time we have optimized TryExecute by moving the string generation
code into a single function that is compiled into the vtkm_cont library.
The end result is that the vtkm_rendering library size has been reduced from
12MB to 11MB, and we shave off about 5% of our build time.
Rather than requiring all the arguments to be placed as member variables to
the functor you can now pass extra arguments that will be added to the functor
call signature.
So for example:
vtkm::ForEach(functor, vtkm::TypeListTagCommon(), double{42.0}, int{42});
will be converted into:
functor(vtkm::Int32, double, int)
functor(vtkm::Int64, double, int)
functor(vtkm::Float32, double, int)
functor(vtkm::Float64, double, int)

The speed improvement fix regressed support for non scalar types, this
correct that issue.
The issue was found while trying to bump the VTK-m version inside VTK.
