embed-rust bindgen

[krisbitney]

This PR adds a new interface embed-bindgen and a Rust implementation. The implementations are expected to be called from wrap-abi-bindgen app binding implementations as an optional way to add embedded Wasm wraps to generated types. This PR adds only the Rust implementation, along with modifications to the app-rust bindings wrap to add support for embeds.

The rust-embed-bindgen wrap was e2e tested locally, using the app/rust template in the CLI repo, to ensure correct Rust syntax.

use wrap::embeds;

let mut config = PolywrapClientConfig::new();
config.add_packages(embeds::packages());

PolywrapClient::new(config.into())

Questions

The CI is not currently passing because the wraps were set to depend on wrapscan URIs. I can't upload to wrapscan. Should I use IPFS URIs for now?

Also, I did not add embedded serialized compiled Wasm modules. For that, I think we need a Rust client plugin that performs compilation and serialization.

The Polywrap CLI has also been updated to add a --embed option to the codegen command: polywrap/wrap-cli#1893

Can we avoid making a whole new set of wraps for this, and instead just add this as a feature within the existing abi-bindgen wraps?

Yes, I'll make the changes tomorrow
