[Feature] Expose SQLite-backed Synchronous KV API for Durable Objects

[AsenHu]

Is there an existing issue for this?

• I have searched the existing issues

Description

Durable Objects provide a Synchronous KV API on top of SQLite-backed storage.

However, the Rust worker crate only exposes the asynchronous API.

Request

Expose the Synchronous KV API in Rust for parity with the JavaScript runtime.
