Auto merge of #104688 - flip1995:clippyup, r=Manishearth,flip1995
Update Clippy

r? `@Manishearth`

Sorry for taking so long. There were so many blockers and so little time. This situation should be mitigated with #104007 in the future.

-### What it does
-Checks for format trait implementations (e.g. `Display`) with a recursive call to itself
-which uses `self` as a parameter.
-This is typically done indirectly with the `write!` macro or with `to_string()`.
-
-### Why is this bad?
-This will lead to infinite recursion and a stack overflow.
-
-### Example
-
-```
-use std::fmt;
-
-struct Structure(i32);
-impl fmt::Display for Structure {
-    fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
-        write!(f, "{}", self.to_string())
-    }
-}
-
-```
-Use instead:
-```
-use std::fmt;
-
-struct Structure(i32);
-impl fmt::Display for Structure {
-    fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
-        write!(f, "{}", self.0)
-    }
-}
-```
