Implement Kokkos kernels compatible with GPU : removing all C++ object from kernels (access to class members).
The behavior of NumTraits?<double>::isNan is not correct on GPU, a solution must be found (temporary solution consists in checking that values are not too large).
Revert some CArray_WF introduction in the initialisation (mask management in CGrid).
For a given process, the CArray_WF class can't address host and device. Clients should be compile with a GPU backend, while servers with a CPU backend (serial, openMP).
Some transfer methods of connectors have been duplicated to manage CArray (initialisation) and CArray_WF (workflow).
A gpu_computing parameter (gpu_computing, 0 by default) has been introduced in the generic_testcase to upload field3D management on GPU.
Other xios_send_field have been temporarily disabled.
