[beta] Rename panic_fmt lint to non_fmt_panic

[m-ou-se]

While extending the recently-added panic_fmt lint, we're renaming it to non_fmt_panic to follow the lint naming guidelines: #81645

The panic_fmt lint has not yet reached stable. If we don't do anything, #[allow(panic_fmt)] will work in 1.50, but give an 'unknown lint' warning in 1.51 later. I'm not sure if this warrants a backport to beta, and if it does, whether it'd be best to just rename the lint (as this PR does) or entirely remove the lint from beta. Opening this PR against beta as a possible option. Feel free to close or suggest a different course of action. :)

I would like to see this in 1.50, so beta accepting, but looks like there are some conflicts - @m-ou-se could you resolve those?

If this doesn't get into beta then I think the behavior of doing nothing or silent acceptance etc is fine and doesn't worry me too much. We can always rename the lint without too much hassle IMO.

#81645 (which does the same rename) was merged, hence the conflict. Re-targeted this PR against beta.
