tabs_in_doc_comments: Fix ICE due to char indexing
This is a quick-fix for an ICE in `tabs_in_doc_comments`. The problem
was that we we're indexing into possibly multi-byte characters, such as '位'.

More specifically `get_chunks_of_tabs` was returning indices into
multi-byte characters. Those were passed on to a `Span` creation that
then caused the ICE.

This fix makes sure that we don't return indices that point inside a
multi-byte character. *However*, we are still iterating over unicode
codepoints, not grapheme clusters. So a seemingly single character like y̆ ,
which actually consists of two codepoints, will probably still cause
incorrect spans in the output.

New Lint: `branches_sharing_code`

This lint checks if all `if`-blocks contain some statements that are the same and can be moved out of the blocks to prevent code duplication. Here is an example:

```rust
let _ = if ... {
    println!("Start"); // <-- Lint for code duplication
    let _a = 99;
    println!("End"); // <-- Lint for code duplication
    false
} else {
    println!("Start");
    let _b = 17;
    println!("End");
    false
};
```

This could be written as:

```rust
println!("Start");

let _ = if ... {
    let _a = 99;
    false
} else {
    let _b = 17;
    false
};

println!("End");
```

---

This lint will get masked by the `IF_SAME_THEN_ELSE` lint. I think it makes more sense to only emit one lint per if block. This means that the folloing example:

```rust
if ... {
    let _a = 17;
} else {
    let _a = 17;
}
```

Will only trigger the `IF_SAME_THEN_ELSE` lint and not the `SHARED_CODE_IN_IF_BLOCKS` lint.

Quick fix for the updated website theaming to access the correct css files

This fixes a problem from #7030 that the service used to access css files was blocked by GitHub pages due to `SSL_ERROR_BAD_CERT_DOMAIN`. The css file loading worked fine during local development. The browser probably disabled some security options due to the local address.

This fix works locally and should also work online as it references the direct css files used by the [mdBook User Guide](https://rust-lang.github.io/mdBook/index.html) the disadvantage of this is that refactorings within the mdBook project can have effects on the theme loading of Clippy. This PR is therefor more meant as a quick fix until I find a better solution.

I've tested these changes using the page editor in the browser and can now confirm that they work :)

44e3ccb6dc Rollup merge of #83820 - petrochenkov:nolinkargs, r=nagisa
Remove attribute `#[link_args]`

Closes https://github.com/rust-lang/rust/issues/29596

The attribute could always be replaced with `-C link-arg`, but cargo didn't provide a reasonable way to pass such flags to rustc.
Now cargo supports `cargo:rustc-link-arg*` directives in build scripts (https://doc.rust-lang.org/cargo/reference/unstable.html#extra-link-arg), so this attribute can be removed.

The theme is also stored in the browser to ensure that the next session applies the theme and doesn't burn your eyes out.

We use `if_chain!` a lot. So this enforces some style rules around it, internal only.

Lints when...
* Nested `if`/`if_chain!` can be collapsed
* An `if_chain!` starts with `let` or ends with `let ..; then {..}`
* An `if_chain!` has only one `if`
* An `if_chain!` contains `if .. && ..;` that spans multiple lines
