Add CUDA backend implementation for AddTraceIntegral

Issue/feature addressed

The AddTraceIntegral operator was re-factored as general implementation AddTraceIntegralImpl.hpp. For the CUDA backend, this introduces repeated device/host and host/device copies. The same problem will occur with a Kokkos-CUDA backend.

Proposed solution

• Full implement the locTraceToTraceMap in AddTraceIntegralSerialStdMat.hpp
• Add a specialized CUDA backend AddTraceIntegralCUDASumFac.cuh and a specialized Kokkos backend AddTraceIntegralKokkosStdMat.hpp.

Implementation

Tests

• The existing CUDA test is used to test the proposed new implementation
• The existing Kokkos test is now disable as a Kokkos IProductWRTBase operator backend is not yet implemented
