Rollup merge of #82113 - m-ou-se:panic-format-lint, r=estebank

Improve non_fmt_panic lint.

This change:
- fixes the span used by this lint in the case the panic argument is a single macro expansion (e.g. `panic!(a!())`);
- adds a suggestion for `panic!(format!(..))` to remove `format!()` instead of adding `"{}", ` or using `panic_any` like it does now; and
- fixes the incorrect suggestion to replace `panic![123]` by `panic_any(123]`.

Fixes #82109.
Fixes #82110.
Fixes #82111.

Example output:
```
warning: panic message is not a string literal
 --> src/main.rs:8:12
  |
8 |     panic!(format!("error: {}", "oh no"));
  |            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  |
  = note: `#[warn(non_fmt_panic)]` on by default
  = note: this is no longer accepted in Rust 2021
  = note: the panic!() macro supports formatting, so there's no need for the format!() macro here
help: remove the `format!(..)` macro call
  |
8 |     panic!("error: {}", "oh no");
  |           --                  --
