[lworld] RFR: 8366270: [lworld] Fix ClassFile AccessFlagsTest

[Chen Liang]

This is the Valhalla version of [JDK-8337220](https://bugs.openjdk.org/browse/JDK-8337220).
We pass the class file version in ClassFile structures for correct access flag validation. Since we are a few tags behind there will be some merge conflict if we pull mainline.
