Currently, we use `VsyncTaskManager::DidRunTask` to change state from `RunVsync` to `NoPendingVsync`, however, the issue is that if the vsync starts an event loop (for instance, by using requestAnimationFrame), and the event loop starts another input task, Firefox crashes because input tasks don't expect the state to be `RunVsync`. So instead of using `DidRunTask`, we start to use `WillRunTask` to fix it. Differential Revision: https://phabricator.services.mozilla.com/D113613
