Bug report

Bug description:

The POSIX functions preadv(), readv(), pwritev(), and writev() don't work as expected under WASI 0.2 on wasmtime. Since there are no plans to change that as their semantics are still POSIX-compliant, we should turn them off for WASI via https://github.com/python/cpython/blob/main/Tools/wasm/config.site-wasm32-wasi .
