Adam Cozzette cbb3edd86d Rust C++: get all map fields onto a common implementation of ProxiedInMapValue This CL migrates messages, enums, and primitive types all onto the same blanket implementation of the `ProxiedInMapValue` trait. This gets us to the point where messages and enums no longer need to generate any significant amount of extra code just in case they might be used as a map value. There are a few big pieces to this: - I generalized the message-specific FFI endpoints in `rust/cpp_kernel/map.cc` to be able to additionally handle enums and primitive types as values. This mostly consisted of replacing `MessageLite*` parameters with a new `MapValue` tagged union. - On the Rust side, I added a new blanket implementation of `ProxiedInMapValue` in rust/cpp.rs. It relies on its value type to implement a new `CppMapTypeConversions` trait so that it can convert to and from the `MapValue` tagged union used for FFI. - In the Rust generated code, I deleted the generated `ProxiedInMapValue` implementations for messages and enums and replaced them with implementations of the `CppMapTypeConversions` trait.
