[lworld] RFR: 8281463: [lworld] VALUE / PRIMITIVE modifiers should be supported by reflection [v2]

[Roger Riggs]

> Add support to java.lang.reflect.AccessFlag ACC_IDENTITY, ACC_VALUE, and ACC_PRIMITIVE.
> Added corresponding flags to j.l.reflect.Modifier so the "source" of the AccessFlag is the Modifer mask.
> Remove PERMITS_VALUE; moving the definition used by HotSpot to HotSpot code.
> 
> Add comments to java.l.reflect.Modifier suggesting use of AccessFlag instead and limitations.
