Like replace(..., ""), but doesn't result in any allocations.

I started implementing this in #50015 but got stuck, mainly because of limitations in the Pattern APIs.

let mut s = String::from("Trees are not green, the sky is not blue.");
s.remove_matches("not ");
assert_eq!("Trees are green, the sky is blue.", s);

Implement String::remove_matches

Closes rust-lang#50206.

I lifted the function help from `@frewsxcv's` original PR (rust-lang#50015), hope they don't mind.

I'm also wondering whether it would be useful for `remove_matches` to collect up the removed substrings into a `Vec` and return them, right now they're just overwritten by the copy and lost.
