wined3d: Use an aux buffer as blitting helper if available.
This helps performance a bit because the function does not have to
wait for the 2nd read to finish before returning. Only do that if we
have an aux buffer to mess with for free though.
To reproduce this bug, download Knight Rider Demo (you can find the link in the
URL field, ~100 MiB), run it, set detail level to Super and color depth to 32
bit then wait while introduction cutscene completes (it is very short but
because of extreme slowdown it may take about 1-2 minutes to complete). When
cutscene ends try to do something - you will see that everything very slow
(about 1 FPS or less).
Without this "bad commit" everything runs smoothly with a lot of FPS (except
cutscene in the beginning, - this is why you need to wait while it ends to see
this bug, - and some situations in game but these ones is different bugs and I
will report them separately when this bug will be fixed).
