Andrew Brown a7f592a026 Add a crate to interface with the WebAssembly spec interpreter
The WebAssembly spec interpreter is written in OCaml and the new crate
uses `ocaml-interop` along with a small OCaml wrapper to interpret Wasm
modules in-process. The build process for this crate is currently
Linux-specific: it requires several OCaml packages (e.g. `apt install -y
ocaml-nox ocamlbuild`) as well as `make`, `cp`, and `ar`.

//! This library provides a way to interpret Wasm functions in the official Wasm
//! specification interpreter, written in OCaml, from Rust.
//!
//! In order to not break Wasmtime's build, this library will always compile. It
//! does depend on certain tools (see `README.md`) that may or may not be
//! available in the environment:
//! - when the tools are available, we build and link to an OCaml static
//! library (see `with_library` module)
//! - when the tools are not available, this library will panic at runtime (see
//! `without_library` module).
/// Enumerate the kinds of Wasm values.
