Previously, we generated no code for non-Wasm platforms; which meant our codegen tests weren't really testing much as far as streams and futures go. Now that the tests actually do something, they uncovered a few issues which I've fixed: - Invalid code generation when using `duplicate_if_necessary: true` - Invalid code generation for stream or futures whose payloads contain one or more a streams or futures For the latter, I mimicked what we do for resources: use interior mutability to provide `take_handle` methods for `StreamReader` and `FutureReader`.

Previously, we would optimistically lower all the values in the input array and then re-lower the subset which wasn't accepted the first time. Aside from being inefficient, that was also incorrect since re-lowering would fail in the cases of any resource handles, futures, or streams in the payload since we would have already taken the handles using `take_handle`.
