[roll] Roll fuchsia Reland "[escher][test] Fix memory leak in rainfall_demo."

This is a reland of 28264db26297c96baf38d9de0048a60bad66bbe1

There was a name conflict in escher rainfall example where
both rainfall Scene and waterfall Scene used the same class
name and caused linkage error (and thus timeout on debug
builders). This change fixes it as well.

Original change's description:
> [escher][test] Fix memory leak in rainfall_demo.
>
> We should use unique_ptr to store demo scenes so that
> it will be destroyed when the rainfall demo is terminated.
> Otherwise it will cause memory leak.
