Make multiple imports of the same header only parse it once per C++ domain. Reuse of the same header in `--share-cpp-ast` mode now reuses the representation. Importing a Carbon file with C++ dependencies now makes those transitive C++ dependencies in the same C++ domain visible too. Assisted-by: Gemini via Antigravity
