Add OrderingBarrierCHROMIUM API.
Implements a GPU Channel level command buffer barrier, which ensures
ordering between channels, without immediately notifying the GPU service.
Multiple Ordering Barriers can be combined into single IPCs to the GPU
service, thus this API can be used in place of ShallowFlushCHROMIUM, to
reduce IPC count and GPU service overhead.
