s/ `String` / `Rc<str>` / in `NamespaceQualifier` and `ir::Identifier`. This CL was motivated by trying to improve the efficiency of `NamespaceQualifier`'s `Clone` implementation - cloning of `Rc<str>` requires just increasing the ref-count and is therefore cheaper than cloning of `String` which requires a heap allocation and copying the string contents. This CL also changes the type of `ir::Identifier` because this is the representation of `ir::Namespace::name`. `Rc<str>` instead of `String` is possible because these strings are never mutated.

Extremely experimental interop tooling for C++ and Rust.
Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.
