By adding an `ImportDecl` instruction, this creates something that can be referenced through `ImportIRInst`. packages/no_prelude/implicit_imports_entities.carbon is getting a test of this (import_conflict and import_conflict_reverse). Also re-packs ImportIR from 24 bytes to 16 on 64-bit, since I'm touching everywhere that makes one anyways.
