Update RenderLayerBacking to store backingSharingLayers in a WeakListHashSet
https://bugs.webkit.org/show_bug.cgi?id=261449
Reviewed by Simon Fraser.
Update RenderLayerBacking to store backingSharingLayers in a
`WeakListHashSet<RenderLayer>`
instead of a Vector<WeakPtr<RenderLayer>>. This is beneficial to performance as
we keep
doing linear searches in the vector otherwise.
