ISSUE-9: Update time value from DOMTimeStamp to DOMHighResTimeStamp [Request Animation Frame]

http://www.w3.org/2010/webperf/track/issues/9

Raised by: Jatinder Mann
On product: Request Animation Frame

Per discussion on the mailing list, http://lists.w3.org/Archives/Public/public-web-perf/2012Mar/0017.html, we need to update the callback parameters time value from DOMTimeStamp to DOMHighResTimeStamp.

The spec should be updated from:

callback FrameRequestCallback = void (DOMTimeStamp time);

To:

callback FrameRequestCallback = void (DOMHighResTimeStamp time);
