Store a `Symbol` instead of an `Ident` in `AssocItem`
This is the same idea as #92533, but for `AssocItem` instead
of `VariantDef`/`FieldDef`.
With this change, we no longer have any uses of
`#[stable_hasher(project(...))]`

This does not take into account the return type of the function currently, so `(&Vec<_>) -> &Vec<_>` functions may still be false positives.
The name given for the type also has to match the real type name, so `type Foo = Vec<u32>` won't trigger the lint, but `type Vec = Vec<u32>` will. I'm not sure if this is the best way to handle this, or if a note about the actual type should be added instead.

Don't suggest an empty variant name in `enum_variant_names`
changelog: false positive fix: [`enum_variant_names`]: No longer suggests an empty variant name
Fixes#8324
This commit changes the behavior of `single_match` lint.
After that, we won't lint non-exhaustive matches like this:
```rust
match Some(v) {
Some(a) => println!("${:?}", a),
None => {},
}
```
The rationale is that, because the type of `a` could be changed, so the
user can get non-exhaustive match after applying the suggested lint (see
https://github.com/rust-lang/rust-clippy/issues/8282#issuecomment-1013566068
for context).
We also will lint `match` constructions with tuples. When we see the
tuples on the both arms, we will check them both at the same time, and
if they form exhaustive match, we could display the warning.
Closes#8282

Add `msrv` config for `map_clone`
Just a small PR to have some fun with Clippy and to clear my head a bit 😅

Out of cycle Clippy update
I want to do an out-of-cycle sync for rust-lang/rust-clippy#8295, and possibly backport this to stable together with https://github.com/rust-lang/rust/issues/92938. If this doesn't get backported to stable, then I at least want to backport it to beta.
