Redesigns the TBB and Serial backends and the vtkm::exec::Task concept so that we can re-use the same launching logic for all Worklets, instead of generating per worlet code. To keep the performance the same the TilingTask now is past a range of indices to work on, rather than a single index. Binary size reduction: WorkletTests_SERIAL old - 19MB WorkletTests_SERIAL new - 18MB WorkletTests_TBB old - 39MB WorkletTests_TBB new - 18MB libvtkAcceleratorsVTKm old - 48MB libvtkAcceleratorsVTKm new - 19MB
