[lworld] RFR: 8281463: [lworld] VALUE / PRIMITIVE modifiers should be supported by reflection [v11]

[Roger Riggs]

> Add support to java.lang.reflect.AccessFlag ACC_IDENTITY and ACC_VALUE.
> Added corresponding flags to j.l.reflect.Modifier so the "source" of the AccessFlag is the Modifier mask.
> 
> Add comments to java.l.reflect.Modifier suggesting use of AccessFlag instead and limitations.

Roger Riggs has updated the pull request incrementally with one additional commit since the last revision:

  Revert additions of ACC_PRIMITIVE to Modifier and AccessFlags.
  The design is in flux.
