devlink: define enum for attr types of dynamic attributes
Devlink param and health reporter fmsg use attributes with dynamic type which is determined according to a different type. Currently used values are NLA_*. The problem is, they are not part of UAPI. They may change which would cause a break. To make this future safe, introduce a enum that shadows NLA_* values in it and is part of UAPI. Also, this allows to possibly carry types that are unrelated to NLA_* values.
