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

[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?)


Thanks,
Yang
