RFR: 8320396: Class-File API ClassModel::verify should include checks from hotspot/share/classfile/classFileParser.cpp [v4]

[Adam Sotona]

> ClassFile API `jdk.internal.classfile.verifier.VerifierImpl` performed only bytecode-level class verification.
> This patch adds `jdk.internal.classfile.verifier.ParserVerifier` with additional class checks inspired by `hotspot/share/classfile/classFileParser.cpp`.
> 
> Also new `VerifierSelfTest::testParserVerifier` has been added.
> 
> Please review.
> 
> Thanks,
> Adam
