Support indirect C++ dependency by sharing domains more broadly (#7763)
Fixes #7731, at least under `--share-cpp-ast` which is expected to be the future direction. When --share-cpp-ast is enabled and any compilation unit has C++ imports, include all compilation units in the shared CppDomain inputs and assign the domain to every unit. In ImportCpp, when a unit has no direct C++ imports but is covered by a shared CppDomain, initialize its C++ AST context and import namespace. This ensures units without direct C++ imports have access to the C++ AST and code generator when instantiating generics or referencing declarations from units that do.
