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.

Do not expand macros in equatable_if_let suggestion
Fixes#7781
Let's use Hacktoberfest as a motivation to start contributing PRs myself again :)
changelog: [`equatable_if_let`]: No longer expands macros in the suggestion
Allow giving reasons for `disallowed_types`
Similar to #7609 but for the `disallowed_type` lint. The permitted form of configuration is the same as for `disallowed_methods`.
changelog: Allow giving reasons for [`disallowed_type`]
Fix FP in external macros for `mut_mut` lint
Fix FP in `mut_mut` lint when type is defined in external macros.
fixes: #6922

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.

Fix false positive when `Drop` and `Copy` involved in `field_reassign_with_default` lint
Fix FP in `field_reassign_with_default` lint when type implements `Drop` but not all fields are `Copy`.
fixes: #6312
changelog: [`field_reassign_with_default`] Fix FP when `Drop` and `Copy` are involved
Don't trigger semicolon_if_nothing_returned in expanded code
Fixes#7768
Before, this lint didn't trigger on macros. With rust-lang/rust#88175
this isn't enough anymore. In this PR a `WhileLoop` desugaring kind was
introduced. This overrides the span of expanded expressions when
lowering the while loop. So if a while loop is in a macro, the
expressions that it expands to are no longer marked with
`ExpnKind::Macro`, but with `ExpnKind::Desugaring`. In general, this is
the correct behavior and the same that is done for `ForLoop`s. It just
tripped up this lint.
