Rollup merge of #64799 - Aaron1011:fix/double-panic, r=Mark-Simulacrum
Fix double panic when printing query stack during an ICE On the latest nightly, any call to `bug` or `span_bug` will result in two panics - the first one as a normal result of calling `bug` / `span_bug`, and the second as a result of trying to print the query stack from the panic handler. This is caused by the query-printing code attempting to acquire a lock on `HandlerInnder`, which is still being held by `bug`. This PR moves the actual panic out of `HandlerInner`, into `Handler`. This allows us to release the lock on `HandlerInner` before triggering the panic, ensuring that the panic handler will be able to acquire the lock if necessary.
