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.
