Add these interfaces to the core library. For now, they're two separate interfaces because we don't yet support one interface extending another. This collapses a lot of the layering in check: for example, the call building logic depends on implicit conversions, conversions now depend on the overloaded operator machinery, and that machinery depends on building calls. In passing, improve the diagnostics for failing to find a name required from the prelude. Also convert all the transitively-called code from `NodeId` to `LocId` given the latter is what the conversion machinery has available. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
