Add lint for debug_assert_with_mut_call

closes #1526

**What does not work:**

* detecting a mut call in the format string itself, e.g. `debug_assert!(false, "{}", vec![1].pop())`
* detecting `*mut T` usage (pointer)

Fix suggestion of `explicit_counter_loop`

changelog: In the suggestion of `explicit_counter_loop`, if the `for` loop argument doesn't implement `Iterator`, then we suggest `x.into_iter().enumerate()` (or `x.iter{_mut}()` as appropriate). Also, the span of the suggestion has been corrected.

5572476a36 Add lint for debug_assert_with_mut_call 
This lint will complain when you put a mutable function/method call
inside a `debug_assert` macro, because it will not be executed in
release mode, therefore it will change the execution flow, which is not
wanted.

cc622608db new lints around #[must_use] fns 
`must_use_unit` lints unit-returning functions with a `#[must_use]`
attribute, suggesting to remove it.

`double_must_use` lints functions with a plain `#[must_use]`
attribute, but which return a type which is already `#[must_use]`,
so the attribute has no benefit.

`must_use_candidate` is a pedantic lint that lints functions and
methods that return some non-unit type that is not already
`#[must_use]` and suggests to add the annotation.

<!--
Thank you for making Clippy better!

We're collecting our changelog from pull request descriptions.
If your PR only updates to the latest nightly, you can leave the
`changelog` entry as `none`. Otherwise, please write a short comment
explaining your change.

If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.

If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.

- [x] Followed [lint naming conventions][lint_naming]
- [x] Added passing UI tests (including committed `.stderr` file)
- [ ] `cargo test` passes locally
- [x] Executed `./util/dev update_lints`
- [ ] Added lint documentation
- [ ] Run `./util/dev fmt`

[lint_naming]: https://rust-lang.github.io/rfcs/0344-conventions-galore.html#lints

Note that you can skip the above if you are just opening a WIP PR in
order to get feedback.

Delete this line and everything above before opening your PR -->

- [x] suggest replacing `assert!(false, "msg")` with `panic!("msg")`
- [x] extend to allow ~~variables~~ any expression for `"msg"`

4c881d108a clippy::cargo_common_metadata: check for license-file 
When license property is missing in Cargo.toml check for license-file
as it may be used instead of the former. The check implemented here is
very naive as it only verifies that the field is present and is not
empty. More scrutiny can be applied by verifying the file is actually
present.

#4542 remove machine applicable suggestion

This helps #4542 (but does not completely resolve) by removing the machine applicable suggestion (which was incorrect) for that case.

I would have preferred to fix the machine applicable suggestion to handle format strings, but that's a bit beyond my current understanding of the clippy codebase. I'd be happy to give it a try given some guidance.

Changes cast-lossless to a pedantic lint

As discussed in #4528, this moves the cast-lossless lint from `all` to `pedantic`.

I couldn't tell from description alone if it should also be removed from the complexity category, so I left it as part of complexity for now. I didn't see any impact to the tests from this change, but I could be wrong (as this is my first PR).

fixes #4528

changelog: Moves cast-lossless from default to checking only as a `pedantic` lint.

Allow block_in_if_{stmt,expr} in external macro

I found this by running `cargo fix --clippy` on quite a big codebase.

You could refactor this assert to
```rust
let block_expr = _;
assert!(block_expr);
```

but,
1. it doesn't increase the readability IMO
2. That isn't possible in a `debug_assert!`

I'm not sure though, if we should allow this for macros in general or just for external macros.

This removes the `Vec<Symbol>` allocation. We still need to call `cx.get_def_path`, but this should already have been interned, and I don't see how we can keep ergonomics of that function without allocating a `Vec`.

Thank you for making Clippy better!

We're collecting our changelog from pull request descriptions.
If your PR only updates to the latest nightly, you can leave the
`changelog` entry as `none`. Otherwise, please write a short comment
explaining your change.

If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.

If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.

- [ ] Followed [lint naming conventions][lint_naming]
- [ ] Added passing UI tests (including committed `.stderr` file)
