When declaring an associated entity in an interface -- just associated functions for now -- create an associated entity value and corresponding type to represent a "slot in a witness table". Also track the list of associated entities on the interface so that we will eventually be able to check impls against them. Associated entities are represented as the integer index of their slot in a witness table. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
