Fields and Ids of enum variants and structs

For enum variants: NodeId represents both an Id of the variant itself (relevant for all variant kinds) and an Id of the variant's constructor (not relevant for Struct-variants). One shared Id can be successfully used for these two purposes. Id of the whole enum lives in Item.

For structs: NodeId represents an Id of the structure's constructor, so it is not actually used for Struct-structs (but still presents). Structures don't have an analogue of "Id of the variant itself" from enum variants. Id of the whole struct lives in Item.
