[lworld] RFR: 8292630: [lworld] javac is accepting annotation interface declarations with modifiers: identity and value

[Vicente Romero]

Please review this fix which is syncing the compiler implementation with the spec. The current spec [1] mentions that:

   * It is a compile-time error if an annotation interface declaration has the modifier sealed, or non-sealed, identity, or value (9.1.1.4).

So code code like:

value @interface I {} and
identity @interface I {}


should be rejected by the compiler.
