feat: Add wasi compatibility.

- wasip2 will require +nightly until rust-lang/rust#130323 is resolved and/or std::os::wasip2 is available in stable.
- Support was added to rustix for version 0.38.39 bytecodealliance/rustix#1205
- Support was added to tempfile for version 3.14 Stebalien/tempfile#305
