This pull request implements the specfem::domain::impl::kernels class. Perviously we used virtual pointers on elements, sources and receivers to implement the physics related to different elements. However, on GPUs this is very inefficient. This update implements the templated kernels class which describes the kokkos parallelism and generates separate kernels for different types of elements. This restores the optimal performance achieved from working-operator-implementation branch.
