Currently, unified IR takes a simple approach of generating method wrappers for every anonymous type that it sees. This is correct, but spends a lot of time in code generation and bloats the object files with duplicate method wrappers that the linker discards. This CL changes it to distinguish anonymous types that were found in imported packages vs the local package. The simple win here is that now we stop emitting wrappers for imported types; but by keeping track of them and marking them as "have" instead of "need", we can avoid emitting wrappers for types that appear in both the local package and imported packages. This can be improved further, but this is a simple first step that prevents large protobuf projects from blowing up build cache limits.
