* federation: add support for Apollo Federation subgraph spec v2.3

Updates `federation` module to support Apollo Federation subgraph spec v2.3

Changes:
* v2.2 - update `@shareable` definition to be repeatable to allow annotating both types and their extensions (NOTE: this functionality is not applicable to `graphql-kotlin`)
* v2.3 - adds new `@interfaceObject` directive that allows you to extend interface entity functionality in subgraphs, i.e. by applying `@interfaceObject` directive on a type we provide meta information to the composition logic that this entity type is actually an interface in the supergraph. This allows us to extend interface functionality without knowing any of its implementing types.

* fix integration tests

* update remaining fed2.1 references with fed2.3

* update composition test to use latest router

* update test schema to fed 2.3

* fix directive definitions

* fix tests

* fix definitions

* add missing intf object IT

[federation] add support for Fed 2.1 (ExpediaGroup#1591)

By default, Supergraph schema excludes all custom directives. Federation 2.1 adds new `@composeDirective` that can be used to instruct composition logic to preserve custom directives in the Supergraph schema.

```graphql
directive @composeDirective(name: String!) repeatable on SCHEMA
```
