When a library requires reading some command line arguments through a
function like Initialize, it is typical that it will parse through
arguments it supports and then remove those arguments from argc and argv
so that the remaining arguments can be parsed by the calling program.
VTK-m's initialize did not do that, so add that functionality.
Also
- Renamed vtkm::cont::make_DeviceAdapterIdFromName to just overload
make_DeviceAdapterId.
- Refactored CMake logic for unit tests
- Since we're now querying the device tracker for the names, they
cannot be all caps.
- Updated usages of InitLogging to use Initialize instead.
- Added changelog.
