refactor(schema_derive): use a smarter algorithm for auto-generated trait bounds

[DCNick3]

Context

Part of the solution for #5130.

Solution

This PR changes the way iroha_schema_derive generates trait bounds to the same algorithm that is used by parity-scale-codec.

In general, it adds a bound on IntoSchema for types of all the fields that use the generic parameters, with some special handling for #[codec(skip)], #[codec(compact)] and recursive types.

See docs for trait_bounds::add for more details.

All of the #[schema(bounds = ...)] attributes are removed now, as there's no need for them anymore.

Review notes

• beware: if refactor(schema_derive): use error emitter instead of bailing out early #5131 hasn't been merged yet, the commits for that PR will be included in the diff
