Don't rely on null::Queue::Submit resolving mapping operations.

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).
