Fix the progress message for `x doc rustc`
This makes it more clear that we're using stage 0 *to document* rustc, not that we're documenting stage0 rustc itself.
It also fixes a bug in `msg_sysroot_tool` that would print `Docing`, and removes the `Debug` impl for `Kind` to make sure it doesn't happen again.
Before:
```
Documenting stage0 compiler {rustc-main} (aarch64-apple-darwin)
```
After:
```
Documenting compiler {rustc-main} (stage0 -> stage1, aarch64-apple-darwin)
```
thanks `@BoxyUwU` for catching this!
Fix Assist "replace named generic type with impl trait"
This is a follow-up PR to fix the assist "replace named generic type with impl trait" described in #14626 to filter invalid param types. It integrates the feedback given in PR #14816 .
The change updates the logic to determine when a function parameter is safe to replace a type param with its trait implementation. Some parameter definitions are invalid & should not be replaced by their traits, therefore skipping the assist completely.
First, all usages of the generic type under the cursor are determined. These usage references are checked to see if they occur outside the function parameter list. If an outside reference is found, e.g. in body, return type or where clause, the assist is skipped. All remaining usages need to appear only in the function param list. For each usage the param type is further inspected to see if it's valid. The logic to determine if a function parameter is valid, follows a heuristic and may not cover all possible parameter definitions.
With this change the following param types (as given in [this comment](https://github.com/rust-lang/rust-analyzer/pull/14816#discussion_r1206834603)) are not replaced & therefore skip the assist.
```rust
fn foo<P: Trait>(
_: <P as Trait>::Assoc, // within path type qualifier
_: <() as OtherTrait<P>>::Assoc, // same as above
_: P::Assoc, // associated type shorthand
_: impl OtherTrait<P> // generic arg in impl trait (note that associated type bindings are fine)
_: &dyn Fn(P) // param type and/or return type for Fn* traits
) {}
```
Clippy Book Chapter Updates Reborn: Refresh Lint Configuration's looks
This PR modernizes and clears up some confusion with the "Lint Configuration Options" chapter from the book.
### Changes
- **Remove 'Option - Default Value" table**
- Why was it even there?
- It shouldn't be the first thing an user sees when they enter the chapter. It's clunky, ugly and not useful. The default values for configs are stated in a per-config basis if needed.
- **Add a simple description of what the chapter contains, and the scheme of each configuration option**
- **Minor formatting, mainly adding code fragments to code text**
- It seemed weird and jarring not having back-ticks on text like "arithmetic_side_effects".
- Improves readability and separation between configs.
- **Separate a little bit the Affected Lints list + "Affected lists" message**
- Not having something indicating that the list is about the lints that use the configuration option is confusing.
- It isn't as important as the description and example. Therefore should be separated a little bit imo

This is an independent effort from #10597, but as it's still a Book Chapter Update, I thought it would be cool to include it here. I'm going to keep the reviewing process for this PR to rustbot's desires.

The change updates the logic to determine if a function parameter is
valid for replacing the type param with the trait implementation.
First all usages are determined, to check if they are used outside the function
parameter list. If an outside reference is found, e.g. in body, return type or
where clause, the assist is skipped. All remaining usages only appear in the
function param list. For each usage the param type is checked to see if
it's valid.
**Please note** the logic currently follows a heuristic and may not cover
all existing parameter declarations.
* determine valid usage references by checking ancestors (on AST level)
* split test into separate ones
add checking for cfg(features = ...)
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: [`maybe_misused_cfg`]: check if `#[cfg(feature = "...")]` misused as `#[cfg(features = "...")]`
I've found that there is no indication when `#[cfg(features = "...")]` is used incorrectly, which can easily make mistakes hard to spot. When I searched for this code on github, I also found many misuse cases([link](https://github.com/search?q=%23%5Bcfg%28features+language%3ARust&type=code)).

Add spans to `clippy.toml` error messages
Adds spans to errors and warnings encountered when parsing `clippy.toml`.
changelog: Errors and warnings generated when parsing `clippy.toml` now point to the location in the TOML file the error/warning occurred.
