[lworld] RFR: 8263568: [lworld] Fix residual reference to 'value' [v2]

[Yi Yang]

> javap tool is still outputting primitive type class modifiers as `value` class, it looks like we should tweak this.
> 
> (Actually, I'm wondering what's the meaning of 'native' for fields that annotated with ACC_PRIMITIVE in flagToModifier? Should we remove it and change the `case 0x100` to `case ACC_PRIMITIVE` so that IDE will help us find all references if we want to do some code refactor in the future?)
