Auto merge of #32282 - sfackler:panic-hook, r=alexcrichton

Adjustments to the panic hook API

Rename `set_handler` and `take_handler` to `set_hook` and `take_hook` since we're not actually "handling" (i.e. fixing) anything.

Also alter `set_hook` to take a `Box<Fn(&PanicInfo) + 'static + Sync + Send>` rather than a parameterized closure since there's otherwise no easy way to re-register a hook that came from `take_hook`.
