Initially, the probe filter would simply not set a value if a sample was
outside the input `DataSet`. This is not great as the memory could be
left uninitalized and lead to unpredictable results. The testing
compared these invalid results to 0, which seemed to work but is
probably unstable.
This was partially fixed by a previous change that consolidated to
mapping of cell data with a general routine that permuted data. However,
the fix did not extend to point data in the input, and it was not
possible to specify a particular invalid value.
This change specifically updates the probe filter so that invalid values
are set to a user-specified value.

We now use SumYAxis when executing with CUDA for better memory patterns.
Instead of using the heavy Pass4/Pass4WithNormals, CUDA now uses a
2 pass approach with the second pass outputting the normals and
coordinates using with significantly less warp divergence
The only reason Keys has a template is so that it can hold a UniqueKeys
array and provide the key for each group. If that is not needed and you
want to implement a library function that takes a keys object, you can
now grab the Keys superclass KeysBase. KeysBase is not templated, so you
can pass it to a standard method in a library.
The version of `Filter::Execute` that takes a policy as an argument is now
deprecated. Filters are now able to specify their own fields and types,
which is often why you want to customize the policy for an execution. The
other reason is that you are compiling VTK-m into some other source that
uses a particular types of storage. However, there is now a mechanism in
the CMake configuration to allow you to provide a header that customizes
the "default" types used in filters. This is a much more convenient way to
compile filters for specific types.
One thing that filters were not able to do was to customize what cell sets
they allowed using. This allows filters to self-select what types of cell
sets they support (beyond simply just structured or unstructured). To
support this, the lists `SupportedCellSets`, `SupportedStructuredCellSets`,
and `SupportedUnstructuredCellSets` have been added to `Filter`. When you
apply a policy to a cell set, you now have to also provide the filter.

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.

The `ArrayHandleStreaming` class stems from an old research project
experimenting with bringing data from an `ArrayHandle` in parts and
overlapping device transfer and execution. It works, but only in very
limited contexts. Thus, it is not actually used today. Plus, the feature
requires global indexing to be permutated throughout the worklet
dispatching classes of VTK-m for no further reason.
Because it is not really used, there are other more promising approaches
on the horizon, and it makes further scheduling improvements difficult,
we are removing this functionality.
One of the execution tests, UnitTestScatterAndMaskWithTopology,
was defining a hierarchy of worklets that defined a virtual
operator(). It mostly still worked since the code was executed
with the final type and thus did not actually need to look up
the virtual table. However, some invalid memory access must have
been happening in CUDA since under some unpredictable circumstances
a memory protection error was happening.
This fixes the problem by removing the virtual methods.

Previously, when a ReadPortal or a WritePortal was returned from an
ArrayHandle, it had wrapped in it a Token that was attached to the
ArrayHandle. This Token would prevent other reads and writes from the
ArrayHandle.
This added safety in the form of making sure that the ArrayPortal was
always valid. Unfortunately, it also made deadlocks very easy. They
happened when an ArrayPortal did not leave scope immediately after use
(which is not all that uncommon).
Now, the ArrayPortal no longer locks up the ArrayHandle. Instead, when
an access happens on the ArrayPortal, it checks to make sure that
nothing has happened to the data being accessed. If it has, a fatal
error is reported to the log.
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.
This commit also:
- Removes a corner case not longer used at ArrayPortalGroupVecVariable::get
- Changes doc regarding the number of offset elements in the input
array handler of ConvertNumComponentsToOffsets.
- Updates invokation of make_ArrayGroupVectVariable in multiple files
- Adds its corresponding changelog entry
