[Win] Improvements to run loop timer resolution
https://bugs.webkit.org/show_bug.cgi?id=284823
Reviewed by Yusuke Suzuki.
WM_TIMER has a 10ms resolution, which means we can't hit 60fps on
requestAnimationFrame. By using MsgWaitForMultipleObjectsEx and
maintaining our own timer queue we can get better timer resolution.
