Auto merge of #114005 - Zalathar:no-cstr, r=jackh726
coverage: Don't convert filename/symbol strings to `CString` for FFI LLVM APIs are usually perfectly happy to accept pointer/length strings, as long as we supply a suitable length value when creating a `StringRef` or `std::string`. This lets us avoid quite a few intermediate `CString` copies during coverage codegen. It also lets us use an `IndexSet<Symbol>` (instead of an `IndexSet<CString>`) when building the deduplicated filename table.
