docs: Check if we're in a prerender state, and if we are, set additional timers.
  In Chrome/IE, a prerender state is when a page is completely rendered in an in-memory buffer, before
  a user requests that page.  We do not beacon at this point because the user has not shown intent
  to view the page.  If the user opens the page, the visibility state changes to visible, and we
  fire the beacon at that point, including any timing details for prerendering.
  
  Sets the `t_load` timer to the actual value of page load time (request initiated by browser to onload)
  
  @returns true if this is a prerender state, false if not (or not supported)
