RFR: 8258535: jvm.ClassReader should set the accessor to the corresponding record component

[Vicente Romero]

Please review this fix which addresses a bug in the records implementation. The issue is that when a record is read by jvm.ClassReader, the record components are not linked to its corresponding accessor. If users try to look for the accessor using javax.lang.model API, using an annotation processor for example, then they will find that the accessor is null.

TIA for the review
