RFR: 8339112: Move JVM Klass flags out of AccessFlags [v4]

[Coleen Phillimore]

> Move JVM implementation access flags that are not specified by the classfile format into Klass so we can shrink AccessFlags to u2 in a future change.
> 
> Tested with tier1-7.
> 
> NOTE: there are arm, ppc and s390 changes to this that are just a guess.  Also, graal changes.
