setLayerContentsToImageBuffer async flushes the ImageBuffer, but doesn't wait
for completion.
Reverts the removal of the IPC::Event based implementation of createFlusher for
RemoteImageBufferProxy (removed in 271747@main).
Adds an implemention of PlatformCALayerDelegatedContentsFence that wraps the
ThreadSafeImageBufferFlusher and passes that through to
setRemoteDelegatedContents, so that the remote layer transaction waits on its
completion.
