Trusted<T> is intended to be used as a handle inside of async tasks or inter-thread operations. I see no evidence that the RemovableDomEventListener type is used for either of those; we should be able to store a Dom<EventTarget> value instead and add #[cfg_attr(crown, crown::unrooted_must_root_lint::must_root)] to the struct to allow ./mach build --use-crown to succeed.

There should be no difference in behaviour when running ./mach test-wpt tests/wpt/tests/dom/abort.
