New output binding for Wasm

## Describe the feature

We currently have a middleware that allows modifying requests using Wasm.

Since Dapr implements now a Wasm runtime to support that, would it make sense to have the ability to create a binding to allow running code as Wasm?

This would be an output binding with an `invoke` method that allows triggering code from a Wasm file. It would allow turning Dapr into a Wasm runtime easily.

## Release Note

RELEASE NOTE: **ADD** Wasm output binding

Review the existing middleware that modifies requests using Wasm and Dapr's Wasm runtime first. Define the proposed output binding and its invoke behavior for triggering code from a Wasm file, then establish how completion will be verified for the release-note feature.
