Fixes https://github.com/spring-projects/spring-integration/issues/3765
The `DefaultMethodInvokingMethodInterceptor` has several strategies
for `default` method invocations in the messaging gateway.
One of them is based on the `Lookup` constructor which causes
a `WARNING: An illegal reflective access operation has occurred`.
This can be done lazily when there is no `MethodHandles.privateLookupIn`
in Java version used for the project.
* Fix `OPEN` enum value for the `Constructor<Lookup>` to be resolved in
a lazy manner via `Supplier` and `boolean` flag
**Cherry-pick to `5.5.x`**
