Reviewed by Simon Fraser.
Separating a layer is not free and only visible layers should get this
treatment.
Check the layer visible rect before applying the `isSeparated` property.
* Source/WebKit/UIProcess/RemoteLayerTree/RemoteLayerTreeNode.h:
(WebKit::RemoteLayerTreeNode::shouldBeSeparated const):
(WebKit::RemoteLayerTreeNode::setShouldBeSeparated):
Keep track of the requested separated state on the node like we do for
the visible rect.
* Source/WebKit/Shared/RemoteLayerTree/RemoteLayerTreePropertyApplier.mm:
(WebKit::RemoteLayerTreePropertyApplier::applyPropertiesToLayer):
(WebKit::RemoteLayerTreePropertyApplier::applyProperties):
Only set `separated` on the layer if its visible

Make sure the visible rect is propagated to the UI Process when
separated layers are enabled.

Update the test with an out-of-viewport separated layer.

Introduce a new test where scrolling reveals new separated layers.
