Added support for HIP and hipblas (CUDA and ROC backend)

• We should review (among other things) the codelets definition in runtime_codelets.h as I wasn't sure how we'd want to add hip support in the macro
• Only trsm and gemm has been ported to HIP but more can easily be added
• The trsm and gemm are forced on HIP devices for now (no support for perfmodel in starpu yet)
• I'm not sure what runtime_zlocality.c is used for so I didn't had HIP support for now
• This merge request has been tested against the hip_device_async starpu branch (not merged yet but merge request in progress here)
