Deserialize `Msrv` directly in `Conf`
Gives the error a span pointing to the invalid config value
Also puts `Conf` itself in the `OnceLock` rather than just the `Msrv` for [the `register_late_mod_pass` work](https://github.com/rust-lang/rust/pull/116731) since it will be used from two different callbacks
changelog: none
side effect for `enum_variants`:
use .first() instead of .get(0) in enum_variants lint
move to_camel_case to str_util module
move module, enum and struct name repetitions check to a single file `item_name_repetitions`
rename enum_variants threshold config option
This patch sets the two configuration options for
`undocumented_unsafe_blocks` to `true` by default: these are
`accept-comment-above-statement` and `accept-comment-above-attributes`.
Having these values `false` by default prevents what many users would
consider clean code, e.g. placing the `// SAFETY:` comment above a
single-line functino call, rather than directly next to the argument.
changelog: [`undocumented_unsafe_blocks`]: set
`accept-comment-above-statement` and `accept-comment-above-attributes`
to `true` by default.

Clippy Book Chapter Updates Reborn: Writing tests
This PR adds a new chapter to the book: "Writing tests". The changes have been mainly done from reviews from #9426 and some minor re-writes.
## Notes
- We still need to check that the `git status`es are correct, as `cargo dev new_lint` changed a lot since 2022.
- Requires #10598: Link to "Emitting Lints" where I flagged with `FIXME:`.

Fix SPEEDTEST instructions and output
* `--nocapture` hasn't been needed anymore since forever (even before `ui_test`)
* the result was dividing by 1000 instead of the number of test runs, giving bogus (but still useful for the purpose) timing results.

Add `SPEEDTEST`
In the `master` branch, we currently don't have any way to test the performance of a single lint in changes.
This PR adds `SPEEDTEST`, the environment variable which lets you do a speed test on a lint / category of tests with various configuration options.
Maybe we should merge this with `lintcheck` 🤔
See the book page for more information.

suggests `is_some_and` over `map().unwrap`
changelog: Enhancement: [`option_map_unwrap_or`] now considers the [`msrv`] config when creating the suggestion.
* modified option_map_unwrap_or lint to recognise when an `Option<T>` is mapped to an `Option<bool>` with false being used when `None` is detected; suggests the use of `is_some_and` instead
* msrv is set to 1.70.0 for this lint; when `is_some_and` was stabilised
fixes#9125
