Revert "Remove conditional use of LayerTreeView from RenderWidget."

This reverts commit 2ae8e4805cf3528619e05806e836a78d2c740e0b.

Original change's description:
> Remove conditional use of LayerTreeView from RenderWidget.
> 
> The LayerTreeView is always present since we always composite
> RenderWidgets now (for many years ^_^).
> 
> However, the LayerTreeView *is* removed during shutdown. Most places
> will not need to worry about this because OnClose() drops the IPC
> channel and most uses of LayerTreeView are in response to other IPCs.
> 
> However a few cases involve calls from Blink which could still be
> active in between OnClose() and tearing down the RenderWidget+Blink,
> so in these cases early out if |closing_| which represents better
> conceptually what we're testing.
