feat: add initial wasmcloud wasi kv implementation

[vados-cosmonic]

Feature or Problem

Add an implementation wasi keyvalue contract that allows building fused components.

See the rendered Markdown README for a more thorough explanation.

While the code in there right now errors for all keyvalue interface bits, I will be changing that to wasmbus

Two non-code requests, but I mostly requested changes for cleanliness and language

• Should the Wasm binary files be committed here? Normally we've ignored them but wasn't sure if they were included on purpose
• Can we put this under a top-level folder like wasi-components or something more general, rather than this specific folder? Eventually, I'd hope all our examples can be like this

dismissing requests as they are resolved, but haven't reviewed again to give full approval
