RFR: 8268788: Annotations with lambda expressions can still cause AnnotationFormatError [v4]

[Sergei Ustimenko]

> Change #3294 helps to avoid `AnnotaionFormatException` in `sun.reflect.annotation.AnnotationInvocationHandler.validateAnnotationMethods`. While it fixes the case with e.g. `Runnable`  that generates the synthetic method without parameters, validation still fails on synthetic methods that have parameters e.g. `Function`, `BiFunction`, etc.
> 
> This change removes the restriction on parameters count to be zero i.e. lambdas with parameters
> would be skipped from validation.
