Auto merge of #2449 - oli-obk:ui_test_subtree_sync, r=RalfJung

Use ui_test from crates.io instead of having it in-tree

I have moved a copy of the `ui_test` crate into [a separate repo](https://github.com/oli-obk/ui_test) to facilitate the further non-miri development of it. I will keep syncing until we have reached a point where we don't touch it anymore for miri. At that point we can remove the in-tree version and do further development out of tree.
