This feature adds a new AbortSignal option, named "signal", to the options parameter of addEventListener(). The "signal" option must first be created by an AbortController by accessing the "signal" property on an AbortController instance. Once the signal is passed in to addEventListener, calling "abort()" on the AbortController will remove the event listener added with addEventListener. For more context, see https://github.com/whatwg/dom/issues/911.
