fix memory leaks in generated bindings#153

This addresses a couple of issues: - We weren't freeing canonical ABI results after calling imports and then converting the results to Python values. - We were using the PyO3 `Bound` APIs incorrectly in a few places, resulting in refcounts being incremented too many times. While debugging the latter issue, I took the opportunity to update to the latest PyO3 release, which required addressing the usual API breakage. It also required temporarily forking the repo to add a patch to disable `extern "C-unwind"` in `pyo3_ffi` on `wasm32`. We should be able to drop that fork once we upgrade everything to Python 3.14. Finally, I discovered https://pyo3.rs/v0.25.0/features.html#pyo3_disable_reference_pool which supposedly optimizes Rust<->Python transitions by disabling a feature we don't rely on anyway, so I went ahead and enabled it.
