manual_let_else: do not suggest semantically different replacements

The problem is that this lint does not consider the possibility that the divergent branch can come first and that the patterns may overlap. This led to incorrect suggestions, previously registered as correct in the tests themselves:

```rust
let v = match build_enum() {
    _ => continue,
    Variant::Bar(v) | Variant::Baz(v) => v,
};
```

had a `let Variant::Bar(v) | Variant::Baz(v) = v else { continue; }` suggestion, which is obviously wrong as the original code `continue`s in any case. Issue #10241 gives another example.

The code now checks that the divergent branch comes second. It could be extended later (I've added a TODO) to check for non-overlapping patterns.

Fixes #10241.

Stop bytes_nth from suggesting code that does not compile

Fixes #10151

As discussed in the issue, this PR changes the lint in 2 ways

1. Replace `bytes().nth(n).unwrap()` with `as_bytes()[n]`
2. Replace other `bytes().nth(n)` with `as_bytes().get(n).copied()`

Stop doc_markdown requiring backticks on links to external websites

Fixes #10302

This lint currently checks that any link should be enclosed with `backticks` if the title looks like a lang item. This PR changes the lint to only run on internal links. External links, indicated by `http` or `https`, are skipped.

This PR also reorganises `pulldown_cmark` imports to bypass the clippy lint enforcing 100 line functions.

Add question-mark-used lint

This lint complains when the question mark operator (try operator) is used.  This is a restriction lint that can be useful on local scopes where a custom error handling macro is supposed to be used to augment the error based on local scope data before returning.

Add `let_underscore_untyped`

Fixes #6842

This adds a new pedantic `let_underscore_untyped` lint which checks for `let _ = <expr>`, and suggests to either provide a type annotation, or to remove the `let` keyword. That way the author is forced to specify the type they intended to ignore, and thus get forced to re-visit the decision should the type of `<expr>` change. Alternatively, they can drop the `let` keyword to truly just ignore the value no matter what.

Change unusual_byte_groupings to require byte groupings of equal size

Fixes issue #6556

This lint required byte groupings of size 2 or 4 for `Radix::Binary` and `Radix::Hexadecimal`. Since there are good reasons for allowing groups of other sizes, this PR relaxes the restriction. This lint now requires that

- group sizes after the first group be of the same size and
- greater or equal in size to the first group.

Ignore synthetic type parameters for `extra_unused_type_parameters`

There was a minor bug around calculating spans when forming the help message. An example:

```rust
fn unused_opaque<A, B>(dummy: impl Default) {}
//               ^^ ^
```

In this case, the entire list of generics should be highlighted, instead of each individual parameter. The culprit is the `impl Default`, which registers as a type parameter but doesn't live within the `<...>`. Because synthetic parameters can't ever be manually created, we just ignore them for this lint.
