[rust] Make it easier to test rust client generator (#3543)

As we discovered in #3463, there are various bits of the rust client generator that are currently untested. This PR adds tests for various generator-specific types, and also files.

Follows the example of the rust-server generator for making it easy to add new test specs. This should make it easier for future contributors to make sure that their contributions are tested
