Rollup merge of #137744 - skius:master, r=Nadrieril 
Re-add `Clone`-derive on `Thir`

This PR adds back `Clone` for `Thir`.

If a tool wants to access a `thir_body` query result in the `Callbacks::after_analysis` hook, it can't do so (I think) without a `Clone` impl on `Thir`, because `check_unsafety` steals the value. With `Clone`, the `thir_body` query provider can be overriden to cache a clone of the `Thir`, circumventing that issue.

Specifically, we need it for https://github.com/rust-corpus/qrates, [here](ca7a230196/extractor/src/lib.rs (L205)).

Please let me know if there are issues with this PR/if there's another way to solve the problem at hand
