RFR: 8169629: Annotations with lambda expressions cause AnnotationFormatErrorr

[Joe Darcy]

The stricter checks added by
    8035781: Improve equality for annotations
in creating the proxy objects used to implement annotations has an unintended by-catch of rejecting annotation's whose type has, say, a field initialized with a lambda expression. While uncommon, it is legal code to have a field in an annotation type.

The updated checks skip over the sort of synthetic method used for the initialization.

Some different compilation tactics were used before and after nest mates, so the test includes compilation and testing under both situations.
