For #6830, add support for inline C++ fragments as a declaration rather than as a packaging directive. For now, this uses `inline Cpp <string-literal>;` as syntax. The prior `import Cpp inline <string-literal>;` is left alone for the time being. We can decide separately whether to remove that. `inline Cpp` requires that there was at least one `import Cpp`. It's not clear to me if that's the right design long-term, but it seems reasonable for now. Assisted-by: Gemini via Google Antigravity
