feat(wasmtime-cli): restore support for wasi http module (#6878) (#6974)

* feat(wasmtime-cli): add async support flag

Within the wasmtime CLI, the current default behavior
is to only inject the synchronous functions to linkers.
This will add a flag called `--async` that will inject
the asynchronous one instead.

* chore: refactor wasi http crate

* feat(wasmtime-wasi): make in_tokio function public

* feat(wasi-http): define default feature called sync

* Revert "feat(wasmtime-cli): add async support flag"

This reverts commit b743ff2.

* chore: improve flaky tests for wasi http

* feat(wasi-http): expose sync api for components

* chore: add tests for sync api of wasi http components

* feat(wasmtime-cli): restore support for wasi http module

* chore: revert change to outbound http request invalid test

* chore: have extra tracing to help debugging

* feat(wasi-http): allow modules with sync functions in linker

* fix(wasi-http): missing response body in sync api

* feat: include blocking for io streams

* chore: add tests for wasi http module in cli

* chore: disable preview2 flag in wasi http test

* chore: use preview2 flag in wasi http test

* fix(wasi-http): missing stream output in sync api

* chore: fix tests for wasi http

* chore: add tracing for poll oneoff call

* chore: send exit signal on wasi http test

* chore: swap println to tracing debug

* chore: set http server timeout to 50 secs by default

* chore: add test posting large file

* chore: revert formatting in cargo toml

* chore: fix wasi-http feature and skip failing tests
