Manuel Pégourié-Gonnard c90514ee11 Use MD type not string to in MD test data
For all test that want to use a hash, identify it by its numerical type
rather than a string. The motivation is that when we isolate the
MD-light subset from the larger MD, it won't have support for string
identifiers. Do the change for all tests, not just those that will
exercise functions in MD-light, for the sake of uniformity and because
numerical identifiers just feel better.

Note: mbedtls_md_info_from_string is still tested in md_info().
