Quick: Support reparenting

To support reparenting, we make the compositing surface independent of
the window by using gfx::TEXTURE_TRANSPORT. We also need to be able to
keep frame data across window changes so we can reconstruct the QSGNode
tree in a new context, so extract that data into DelegatedFrameNodeData
class. Any context-specific data is still stored in DelegatedFrameNode.

Also hook up window changes to WebContents::WasShown/Hidden for Quick.
Remove checking of Qt isVisible state, this mechanism is used to sync
Chromium with Qt, not the other way around. WasShown/Hidden is
orthogonal to Show/Hide, and can use different triggers. However for
Widgets it probably makes sense to hook both up to widget visibility.
