[lworld] RFR: 8364095: [lworld] AccessFlags location and release need futher work for Valhalla (IDENTITY and SUPER) [v3]

[Chen Liang]

> Improve access flag reflection for preview on/off.
> 
> In this process, I noted javac is incorrectly injecting ACC_IDENTITY to 69.0 class' `InnerClasses` attribute and fixed that.
> 
> There is still some inconsistency, such as implying ACC_IDENTITY when preview is on for classes. Don't know if we have discussed on this yet.
> 
> No new test failures.
