Proposal: AsyncInfo.Run scenario should be improved when implementation uses generated code

Summary

Today, if the implementation with the AsyncInfo.Run lambda uses other generated code from another generator, we apparently fail to analyze the entire function and generate the necessary vtables for the task adapter classes. But this might be able to be improved if it is in a return statement where we can look at the return type and use that, or maybe we can issue a diagnostic if that fails too.

Rationale

Improve developer experience in these scenarios.
