Clean up requested scroll handling in
RemoteLayerTreeDrawingAreaProxy::commitLayerTreeTransaction()
https://bugs.webkit.org/show_bug.cgi?id=308159

Reviewed by Tim Horton.
iOS has special requirements in
`RemoteLayerTreeDrawingAreaProxy::commitLayerTreeTransaction()`
where it needs to wait until the layer tree commit is done before applying
programmatic scrolls.
Clean this up by moving a chunk of code into the
RemoteScrollingCoordinatorProxy.
Also do some minor cleanup here; remove `ENABLE(ASYNC_SCROLLING)` since that's
always true
for Cocoa platforms. Move `requestedScroll` inside the block.
* Source/WebCore/page/scrolling/AsyncScrollingCoordinator.cpp:
(WebCore::AsyncScrollingCoordinator::requestScrollToPosition): Cleanup to
create the
RequestedScrollData once, then modify it for deltas.
* Source/WebCore/page/scrolling/ScrollingTreeScrollingNode.cpp:
(WebCore::ScrollingTreeScrollingNode::handleScrollPositionRequest): Some extra
logging.
* Source/WebKit/UIProcess/RemoteLayerTree/RemoteLayerTreeDrawingAreaProxy.mm:
(WebKit::RemoteLayerTreeDrawingAreaProxy::commitLayerTreeTransaction):
* Source/WebKit/UIProcess/RemoteLayerTree/RemoteScrollingCoordinatorProxy.cpp:
(WebKit::RemoteScrollingCoordinatorProxy::adjustMainFrameDelegatedScrollPosition):
* Source/WebKit/UIProcess/RemoteLayerTree/RemoteScrollingCoordinatorProxy.h:
