Patch Changes

• Handle defaulted variables correctly during post-processing. (98844fd5)

  Users who tried to use built-in conditional directives (skip/include) with defaulted variables and no variable provided would encounter an error thrown by operation post-processing saying that the variables weren't provided. The defaulted values went unaccounted for, so the operation would validate but then fail an assertion while resolving the conditional.

  With this change, defaulted variable values are now collected and provided to post-processing (with defaults being overwritten by variables that are actually provided).

• Fix issues (incorrectly rejected composition and/or subgraph errors) with @interfaceObject. Those issues may occur (11f2d7c0)
  either due to some use of @requires in an @interfaceObject type, or when some subgraph S defines a type that is an
  implementation of an interface I in the supergraph, and there is an @interfaceObject for I in another subgraph,
  but S does not itself defines I.

• Fix potential bug when an @interfaceObject type has a @requires. When an @interfaceObject type has a field with a (2894a1ea)
  @requires and the query requests that field only for some specific implementations of the corresponding interface,
  then the generated query plan was sometimes invalid and could result in an invalid query to a subgraph (against a
  subgraph that rely on @apollo/subgraph, this lead the subgraph to produce an error message looking like "The _entities resolver tried to load an entity for type X, but no object or interface type of that name was found in the schema").
