Don't clip overflowing Nodes

Summary:
As of D3235050, Nodes supports the optimization of removing clipped
subviews from the hierarchy. However, because Nodes supports overflow:visible,
this could cause issues when DrawCommands overflow the bounds of their parent
container. This patch fixes this by not clipping any overflowing Nodes.
