JVM IR: minor, sort ElementType fields as in the old backend

In the old backend, targets are generated in the order of their
declaration in the ElementType enum, see AnnotationCodegen.java:306
(EnumSet guarantees such iteration ordering).

This has no effect other than reducing non-essential differences when
comparing ABI of JVM vs JVM_IR.
