Fixed naive doc formatting for `#[must_use]` lints
The documentation of a few lints around the `#[must_use]` attribute had a few times "[`#[must_use]`]" (without the parentheses, but with the `[]`) and once the "`" was missing.
changelog: Fixed naive doc formatting for `#[must_use]` lints ([`must_use_unit`], [`double_must_use`], [`must_use_candidate`], [`let_underscore_must_use`])
Add `format_in_format_args` and `to_string_in_format_args` lints
Fixes#7667 and #7729
I put these in `perf` since that was one of `@jplatte's` suggestions, and `redundant_clone` (which I consider to be similar) lives there as well.
However, I am open to changing the category or anything else.

Refactor `clippy::match_ref_pats` to check for multiple reference patterns
fixes#7740
When there is only one pattern, to begin with, i.e. a single deref(`&`), then in such cases we suppress `clippy::match_ref_pats`.
This is done by checking the count of the reference pattern and emitting `clippy::match_ref_pats` when more than one pattern is present.
Removed certain errors in the `stderr` tests as they would not be triggered.
