ASTUnit is owned by `CompileSubcommand`, passed through `Unit` to be populated in `ImportCppFiles()` and used via `SemIR::File`. When generating the AST, pass `-x c++` args to compile C++ (temporary until we pass args properly). `Cpp` namespace is marked as a special namespace and has dedicated logic in `LookupNameInExactScope()`. The logic for importing declarations from C++ to Carbon is in `import_cpp.cpp`, but we're likely to want to refactor this signfiicantly over time as it grows (perhaps a dedicated directory?). Part of #4666.
