Fix clippy::redundant_clone lint violations (#36558)

This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.

A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.

I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.
