Enhancement Request

Due to recent changes in the EventMesh protobuf files, the existing Rust SDK is no longer compatible. Therefore, a refactoring of the Rust SDK is required. The refactoring will be carried out in the following steps:

1. Refactor the gRPC portion of the Rust SDK.
2. Refactor the HTTP portion of the Rust SDK (This work will be done after issue [Feature] Http client optimize #4481 is completed).
3. Add the TCP protocol to the Rust SDK.

Describe the solution you'd like

The refactoring will be carried out in the following steps:

1. [Feature] Rust SDK supports the latest gRPC protocol #4467
2. [Feature] Rust sdk support CloudEvents #4519
3. Refactor the HTTP portion of the Rust SDK.
4. Add the TCP protocol to the Rust SDK.
