We now keep track of any resource/stream/future handles we've lowered while writing to a stream or future and restore any that were unwritten so they can be used (e.g. possibly written) again. While I was working on this, clippy pointed out that `std::io::pipe` (which I started using in a previous commit) was added in Rust 1.87, so I've bumped the MSRV to match. Also, the test case I added to cover this revealed another bug, which I've fixed here: we weren't generating valid code for async functions which return tuples. Fixes bytecodealliance#1458 Signed-off-by: Joel Dice <joel.dice@fermyon.com>
