RFR: 8374654: Inconsistent handling of lambda deserialization for Object method references on interfaces

[Liam Miller-Cushon]

See [JDK-8374654](https://bugs.openjdk.org/browse/JDK-8374654). This fixes an inconsistency between generated Lambda `$deserialization$` methods and the runtime behaviour of `SerializedLambda` instances, for Object method references on interfaces. At runtime the methods are resolved to declared methods, so Object method references on interfaces will always have the `getImplMethodKind`, `getImplClass`, and `getImplMethodSignature` of the method declared in `Object`, not of an override in the interface.
