JDK-8245854 - JVM TI Specification for sealed classes
Description
After the Sealed classes are introduced the jvmtiRedefineClasses.cpp has three functions that check the same:
  check_nest_attributes
  check_record_attributes
  check_permitted_subclasses_attribute

We should refactor it to have just one implementation for this check.

The record attribute has a little bit different layout. It does not look it is worth trying to cover it in this refactoring. The suggested fix is: http://cr.openjdk.java.net/~sspitsyn/webrevs/2020/jvmti-redef-refact.1/
