In the validation tests, we relied on Queue.Submit(0, nullptr) to resolve mapping operations. This is fragile so we replace it with a FlushMappingOperations() function that uses device.Tick() instead. This allows removing the mapSerial argument from Buffer::MapRead/WriteAsyncImpl (which was the actual goal of this CL).
