  [Site Isolation][iOS] Do not update WKContentView bounds when transaction comes from subframe process

Reviewed by Alex Christensen.

We currently change the WKContentView size based on the content size in RemoteLayerTreeTransaction. However, the size
in a subframe process transaction is only about subframe content, so we should not change content view size for that.
Otherwise, the whole web view will be clipped to subframe size.
