Corrects the float_equality_without_abs lint
Fixes an issue in the `float_equality_without_abs` lint. The lint suggestion was configured in a way that it lints the whole error and not just the subtraction part. In the current configuration the lint would suggest to change the expression in a wrong way, e.g.
```rust
let _ = (a - b) < f32::EPSILON; // before
let _ = (a - b).abs(); // after
```
This was dicovered by @flip1995. (See discussion of PR #5952).
Also the suggestion is now formatted via `utils::sugg`.

Fix `let_and_return` bad suggestion
Add a cast to the suggestion when the return expression has adjustments.
These adjustments are lost when the suggestion is applied.
This is similar to the problem in issue #4437.

Fix incorrect suggestion when `clone_on_ref_ptr` is triggered in macros
In the lint `clone_on_ref_ptr`, if the `span` is in a macro, don't expand it for suggestion.

Don't lint if it has always inline attribute
Don't trigger the lint `trivially_copy_pass_by_ref` if it has `#[inline(always)]` attribute.
Note: I am not particularly familiar with `inline` impacts, so I implemented this the way that if only `#[inline]` attribute is here (without `always`), the lint will still trigger. Also, it will still trigger if it has `#[inline(never)]`.
Just tell me if it sounds too much conservative.

Prelude imports are exempt from wildcard import warnings. Until now only
imports of the form
```
use ...::prelude::*;
```
were considered. This change makes it so that the segment `prelude` can
show up anywhere, for instance:
```
use ...::prelude::v1::*;
```
Fixes#5917
Fix false positive in `PRECEDENCE` lint
Extend the lint to handle chains of methods combined with unary negation.
Closes#5924
changelog: Fix false negative in `PRECEDENCE` lint
This extends PR #73293 to handle patterns (Pat). Unlike expressions,
patterns do not support custom attributes, so we only need to capture
tokens during macro_rules! argument parsing.
Warn about assignments where left-hand side place expression is the same
as right-hand side value expression. For example, warn about assignment in:
```rust
pub struct Event {
id: usize,
x: i32,
y: i32,
}
pub fn copy_position(a: &mut Event, b: &Event) {
a.x = b.x;
a.y = a.y;
}
```
