RFR: 8267421: j.l.constant.DirectMethodHandleDesc.Kind.valueOf(int) implementation doesn't conform to the spec regarding REF_invokeInterface handling

[Vicente Romero]

Please review this PR which is just syncing the implementation of DirectMethodHandleDesc.Kind.valueOf(int) with its spec. My reading of the method's spec is that if the value of the `refKind` parameter is: MethodHandleInfo.REF_invokeInterface, then DirectMethodHandleDesc.Kind.valueOf(int, boolean) should be called with a value of `true` for its second argument, currently it is invoked with `false` regardless of the value of the `refKind` parameter

TIA
