[Analysis API decompiler] materialize delegate declarations in stubs

We should materialize delegated declarations to process callables
in scopes correctly. Standalone mode works the same way as it
deserialize directly into FIR.
Another solution is to rework proto and stub serializer/deserializer to
restore FirFields like `$$delegate_0` correctly to work with
`FirDelegatedMemberScope`
