Everywhere: Remove instances of clippy::redundant-clone (#43212)

This change fixes all instances where
[`clippy::redundant-clone`](https://rust-lang.github.io/rust-clippy/master/index.html?groups=complexity%2Ccorrectness%2Cnursery%2Csuspicious&levels=allow#redundant_clone)
would trigger. It's allowed by default

I've also changed the lint to warn-by-default for servo.

Testing: Covered by WPT
