Reduce memory cost of `ObjcLibrary`. `LibraryToLink`'s generated `AutoValue` class contains 20 fields, but `ObjcLibrary` typically only needs two of them - the rest are either `null` or `false`. To accommodate this, introduced a specialized `StaticOnlyLibraryToLink` implementation with only the two necessary fields. We lose out on the memoization of the four `LinkerInputs.LibraryToLink`-returning methods, but for `ObjcLibrary` these are never called multiple times anyway. It seems rare that they are ever called multiple times, but I left the memoization (using `@Memoized` now) for the non-static-only case. To reduce duplicate instances, intern based on the defining `Artifact`. This also takes care of duplicate strings created in `CcLinkerOutputs#libraryIdentifierOf`. Made some other tangentially related optimizations. PiperOrigin-RevId: 361654318
