new lint: `manual_while_let_some`
This PR implements the lint I suggested [on zulip](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/lint.20on.20while.20pop.20unwrap).
It looks for while loops like these:
```rs
let mut numbers = vec![0, 1, 2];
while !numbers.is_empty() {
let number = numbers.pop().unwrap();
// use `number`
}
```
and suggests replacing it with a while-let loop, like this:
```rs
let mut numbers = vec![0, 1, 2];
while let Some(number) = numbers.pop() {
// use `number`
}
```
... which is more concise and idiomatic.
It only looks for `Vec::pop()` calls in the first statement of the loop body in an attempt to not trigger FPs (as pop might only be called conditionally).

Fix `items_after_test_module`: Ignore imported modules
Fixes#10713. It does a little bit of dark magic, but intention is what really counts.

Using `default` to construct a unit struct increases code complexity and
adds a function call. This can be avoided by simply removing the call to
`default` and simply construct by name.
Add configuration for `semicolon_block` lints
Does exactly what it says on the tin, suggests moving a block's final semicolon inside if it's multiline and outside if it's singleline.
I don't really like how this is implemented so I'm not too sure if this is ready yet. Alas, it might be ok.

Switch to `EarlyBinder` for `explicit_item_bounds`
Part of the work to finish https://github.com/rust-lang/rust/issues/105779.
This PR adds `EarlyBinder` to the return type of the `explicit_item_bounds` query and removes `bound_explicit_item_bounds`.

Document that `cargo clippy --fix` implies `--all-targets`
In [`cargo fix`'s documentation](https://doc.rust-lang.org/cargo/commands/cargo-fix.html) they indicate that `fix` implies `--all-targets` if no target is supplied. As Clippy uses Cargo under the hood, this also applies to Clippy, but we didn't document that behaviour.
This PR changes that

Don't apply `string_lit_as_bytes` if in macro expansion
The following code will emit a warning on both w! and h!, despite there being nothing the user (or library author) could do about it:
```rust
#![warn(clippy::string_lit_as_bytes)]
use windows::w;
use windows::h;
fn main() {
let _w = w!("example");
let _h = h!("example");
}
```
This is because windows-rs will create a binding `const INPUT: &[u8] = $s.as_bytes()`, and changing this to b"$s" is, well, suboptimal. I don't know enough about Rust to know if this is something that can be detected though if it can be I'm happy with closing this in favor of implementing that.
I'm not sure whether this is how it should be done though, as this simply tells clippy to not invoke this even if it's applicable (this also affects the other string lints, but didn't cause any tests to fail).
