Add SourceProvider modules which provides a base interface for more complex code generation usecases such as bindgen. Also adds the rust_bindgen module type which calls bindgen to generate Rust FFI bindings to C. Bug: 159064919 Test: Local test module generates bindings. Test: New Soong tests pass.
