[Feature Request] Add Rust SDK for Wasm Plugin Support

[earayu]

Background

WeScale enables the development of Wasm plugins to extend the functionality of the platform. Currently, there is a Golang SDK available for creating Wasm plugins, along with a template for reference.

Proposal

Introduce a Rust SDK to expand the options for writing Wasm plugins in WeScale. By implementing the necessary interfaces between the host and guest environments, developers can leverage Rust for plugin development alongside Golang. This addition will provide more flexibility and choice in plugin development for the WeScale platform.

For additional context:

• Documentation: Wasm Plugin Documentation
• Golang SDK: wescale-wasm-plugin-sdk
• Golang Template: wescale-wasm-plugin-template
• Guest Interfaces: Guest ABI in Golang SDK
• Host Interfaces: Host ABI in Golang SDK, Host Functions ABI in Golang SDK
