fix(federation/stitch/delegate): handle complex nested keys

[ardatan]

If there are some fields depending on a nested type resolution, wait until it gets resolved then resolve the rest.

See packages/federation/test/fixtures/complex-entity-call example for more details.
You can see ProductList needs some fields from Product to resolve first

Closes #6076
