Fix the missing CUDA device qualifier

Reference issue

#2872 (closed)

What does this implement/fix?

• Fixed an issue when calling Eigen::Matrix3f(v.asDiagonal()) in CUDA

  The issue was cause by the usage of non device function Assignment<ActualDstTypeCleaned, Src, Func>::run at Eigen/src/Core/AssignEvaluator.h:829.

  The fix added the EIGEN_DEVICE_FUNC macro at Eigen/src/Core/DiagonalMatrix.h:392.

• Fixed an issue when calling Eigen::Vector3f({{1,2,3}}) in CUDA

  The issue was cause by the usage of non device function internal::check_implication at Eigen/src/Core/PlainObjectBase.h:295 and std::copy at Eigen/src/Core/PlainObjectBase.h:528

  The fix added the EIGEN_DEVICE_FUNC macro at Eigen/src/Core/util/Meta.h:740 and replace std::copy with manual iteration.

  The fix also added the EIGEN_DEVICE_FUNC macro to all the other function definitions in Eigen/src/Core/util/Meta.h.
