[fidl][rust] Eliminate recursive impl bounds

Some FIDL types have recursive definitions, where a trait impl applies
only if it already applies. For impls with no generics, this isn't an
issue since Rust's trait solver automatically applies coinduction to
these trait impls. That doesn't apply for trait impls with generics
though, so we have to avoid those recursive bounds.

During refactoring, a few issues with the trait structure cropped up, so
this addresses a few of those as well.
