Rename art::ReadBarrier::WhiteState as art::ReadBarrier::NonGrayState.
The read barrier state recorded in object's lockword used to be a
three-state value (white/gray/black), which was turned into a
two-state value (white/gray), where the "black" state was conceptually
merged into the "white" state. This change renames the "white" state
as "non-gray" and adjusts corresponding comments.
