REGRESSION(271747@main): [Win][GPUP] Rendering artifact of AC mode
https://bugs.webkit.org/show_bug.cgi?id=266329
Reviewed by Don Olmstead.
After 271747@main removed RemoteImageBufferProxy::createFlusher
implementation, repainting a window caused a rendering artifact for
Windows port. 271803@main and 271892@main were the previous attempt to
fix the problem. But they were wrong fixes.
This problem can be resoved just by using newly added
RemoteImageBufferSetProxy::flushFrontBufferAsync even though Windows
port doesn't use RemoteImageBufferSetProxy yet. Because both
RemoteImageBufferSet and RemoteImageBuffer are using a same
StreamWorkQueue, flushing RemoteImageBufferSet command also ensures
that preceding RemoteImageBuffer commands are also flushed.
