I believe we will need to eventually add the specific C++ import information in `LocId`. This also seems to fix the `LanguageServerDiagnosticInWrongFile` issue (#5604). We're still not in the state we want to be according to https://github.com/carbon-language/carbon-lang/pull/5246#issuecomment-2784301206. Will look into removing the location part from the `"In file included from ..."` line. Part of #5245.
