Avoid waiting on load events

Overview
This audit checks whether or not the first ad request is blocked on a page load
event. Ad requests themselves do not interact with the DOM and are not dependent
on the page being fully loaded. It's therefore recommended to make ad requests
as early as possible to speed up ad loading.
Recommendations
Remove any logic that prevents ad requests from being made before the page
load or domContentLoaded events fire.
