RFR: 8255342: Remove non-specified JVM checks on Classes with Record attributes [v2]

[Harold Seigel]

> Please review this fix to remove the checks for non-final and abstract classes containing Record attributes and checks for classes containing Record attributes whose supers are not java.lang.Record.  These checks are not specified in the JVM Spec and so should not be done by the JVM.
> 
> The change removes the checks and updates Record tests as needed.
> 
> The fix was tested with mach5 tiers 1 and 2 on Linux, Windows, and Mac, and tiers 3-5 on Linux x64 and with JCK lang, vm, and api/java_lang tests.
> 
> Thanks, Harold
