PinchViewport shouldn't resize contents layer on FrameView creation.

Previously, PinchViewport would hear a mainFrameDidChangeSize on the
main frame creating a view. This appears to be unneeded as the compositor
attachment happens after this, if a content layer exists it will be replaced.

This was causing a subtle bug on Android where navigating to a page with smaller
content size would clamp the scroll offset on the current history item. This
happened because setting the FrameView would call FrameLoader::saveScrollState.
During a document load, the FrameView is created before the HistoryItem in
FrameLoader is swapped out. We can avoid this whole situation by simply removing
the call to mainFrameDidChangeSize in LocalFrame::SetView.
