This method only is async in order to allow callers to wait for a process switch triggered by the call to `loadURI` to be finished before resolving. With DocumentChannel, we should never trigger a process switch eagerly like this again, so we don't need any of the async behaviour here anymore. This part is largely mechanical changes to tests, removing the `await` calls on `loadURI`, and a follow-up part will remove the actual async logic from `BrowserTestUtils.loadURI`.
