This commit makes two changes - separating the `NodeId` that identifies an enum variant from the `NodeId` that identifies the variant's constructor; and no longer creating a `NodeId` for `Struct`-style enum variants and structs. Separation of the variant id and variant constructor id will allow the rest of RFC 2008 to be implemented by lowering the visibility of the variant's constructor without lowering the visbility of the variant itself. No longer creating a `NodeId` for `Struct`-style enum variants and structs mostly simplifies logic as previously this `NodeId` wasn't used. There were various cases where the `NodeId` wouldn't be used unless there was an unit or tuple struct or enum variant but not all uses of this `NodeId` had that condition, by removing this `NodeId`, this must be explicitly dealt with. This change mostly applied cleanly, but there were one or two cases in name resolution and one case in type check where the existing logic required a id for `Struct`-style enum variants and structs.
