Add support for the experimental wasi-crypto APIs (#2597)

Browse Source 
* Add support for the experimental wasi-crypto APIs

The sole purpose of the implementation is to allow bindings and
application developers to test the proposed APIs.

Rust and AssemblyScript bindings are also available as examples.

Like `wasi-nn`, it is currently disabled by default, and requires
the `wasi-crypto` feature flag to be compiled in.

* Rename the wasi-crypto/spec submodule

* Add a path dependency into the submodule for wasi-crypto

* Tell the publish script to vendor wasi-crypto

# wasmtime-wasi-crypto
This crate enables support for the [wasi-crypto] APIs in Wasmtime.
The sole purpose of the implementation is to allow bindings and
application developers to test the proposed APIs. This implementation
is not meant to be used in production. Like the specification, it is
currently experimental and its functionality can quickly change.
Since the [wasi-crypto] API is expected to be an optional feature of
WASI, this crate is currently separate from the [wasi-common] crate.
* [documentation]
* [interfaces reference]
* [interfaces reference (compact)]
[wasi-crypto]: https://github.com/WebAssembly/wasi-crypto
[wasi-common]: ../../wasi-common
[documentation]: ../spec/docs/wasi-crypto.md
[interfaces reference]: ../spec/witx/wasi_ephemeral_crypto.md
[interfaces reference (compact)]: ../spec/witx/wasi_ephemeral_crypto.txt
## Wasmtime integration
Use the Wasmtime APIs to instantiate a Wasm module and link the
`wasi-crypto` modules as follows:
```rust
use wasmtime_wasi_crypto::{
WasiCryptoAsymmetricCommon, WasiCryptoCommon, WasiCryptoCtx, WasiCryptoSignatures,
WasiCryptoSymmetric,
};
let cx_crypto = WasiCryptoCtx::new();
WasiCryptoCommon::new(linker.store(), cx_crypto.clone()).add_to_linker(linker)?;
WasiCryptoAsymmetricCommon::new(linker.store(), cx_crypto.clone()).add_to_linker(linker)?;
WasiCryptoSignatures::new(linker.store(), cx_crypto.clone()).add_to_linker(linker)?;
WasiCryptoSymmetric::new(linker.store(), cx_crypto.clone()).add_to_linker(linker)?;
let wasi = wasmtime_wasi::old::snapshot_0::Wasi::new(linker.store(), mk_cx()?);
wasi.add_to_linker(linker)?;
```
## Building Wasmtime
Wasmtime must be compiled with the `wasi-crypto` feature flag
(disabled by default) in order to include the crypto APIs.
## Examples
Example [rust bindings] and [assemblyscript bindings] are provided to
demonstrate how these APIs can be used and exposed to applications in
an idiomatic way.
[rust bindings]: ../spec/implementations/bindings/rust
[assemblyscript bindings]: ../spec/implementations/bindings/assemblyscript
