Adds support for using extern impl blocks to describe methods and static/associated functions on a type.

Requires a companion patch to rustc, so this may take some time to be able to land.

This syntax allows methods in the bridge block to be grouped together by
type and use implicitly typed receivers (e.g. `&self`, `&mut self`, or
`self`) even when multiple types are declared in the same bridge.
Support binding to static methods (C++) and associated methods (Rust) by
using `impl` blocks to indicate which type it belongs to.

See rust-lang/rust#102376 for the companion PR to rustc to make this possible.

Note that there are discussions around possible static methods API here #447, although it's not clear if there was a preferred API.
