Make it not possible to create a cell set without specifying num points The CellSetExplicit and CellSetSingleType classes have an ivar that marks the number of points. There were several instances of code creating cell sets without specifying the number of points. This can be very bad if subsequent code needs that information.

Remove TryExecute from filters Now that the dispatcher does its own TryExecute, filters do not need to do that. This change requires all worklets called by filters to be able to execute without knowing the device a priori.

Merge worklet testing executables into a device dependent shared library VTK-m has been updated to replace old per device worklet testing executables with a device dependent shared library so that it's able to accept a device adapter at runtime. Meanwhile, it updates the testing infrastructure APIs. vtkm::cont::testing::Run function would call ForceDevice when needed and if users need the device adapter info at runtime, RunOnDevice function would pass the adapter into the functor. Optional Parser is bumped from 1.3 to 1.7.
