Currently, VTK-m is using C++11. However, it is often useful to use
features in the `std` namespace that are defined for C++14 or later. We
can provide our own versions (sometimes), but it is preferable to use
the version provided by the compiler if available.
There were already some examples of defining portable versions of C++14
and C++17 classes in a `vtkmstd` namespace, but these were sprinkled
around the source code.
There is now a top level `vtkmstd` directory and in it are header files
that provide portable versions of these future C++ classes. In each
case, preprocessor macros are used to select which version of the class
to use.
Made a new vtkm::Tuple class to replace tao tuple.
This version of Tuple should hopefully compile faster. Having our own
implementation should also make it easier to port to new devices.

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.

Even if an error condition occurs, the output parameter should be
initialized to something. This makes the behavior predicatable on error
conditions and prevents uninitialized variable warnings.
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 change affects the method GetThreadIndices for both
WorkletMapTopology and WorkletPointNeighborhood.
Before an scatter or mask which was not ScatterIdentity or MaskNone
was not allowed and it was enforced at compilation time.

Cell operations like interpolate and finding parametric coordinates can
fail under certain conditions. Typically these call RaiseError on the
worklet. But that can make a worklet unstable, so provide paths where no
error is raised.

When `ArrayPortalToken::Detach` was called, the contained `Token` was
detached, but `ArrayPortal` being wrapped might also be holding its own
portal that it is decorating. To ensure that any dependent portals are
also detached, `ArrayPortalToken::Detach` resets itself.
