Instead of building one Clang `ASTContext` per compilation, the `--share-cpp-ast` flag causes us to build a single `ASTContext` and share it across all contexts. One new abstraction is added: `CppDomain` represents the Carbon-side view of a Clang AST that might be shared across multiple `SemIR::File`s. This object owns the Clang instance and the AST. For now, we have no isolation between the C++ state exposed to different Carbon compilations, and we have no multiplexing of generated LLVM IR from C++ into different Carbon compilations, so the mode is not usable yet. The plan is to keep it behind a flag until it's ready. Assisted-by: Gemini via Antigravity
