Subject: [PATCH] Expose rust code gen of contracts without the file import
 (#1311)

### What
Expose rust code gen of contracts without the file import.

### Why
The code gen function for rust code generates the interface and types as
well as an import of the wasm binary. The CLI uses this function and
wants to output the generated code without the wasm binary.
