Expose RequestComplete time to DRT

Expose RequestComplete time to DRT

Currently loadFinishTime of CachedResource in blink part is always
0 when run layout test case via DRT, while the value is there when
run a real browser. The reason is RequestProxy in testshell use a
blank TimeTicks as request complete time. This issue affects Resource
Timing layout test cases.

code to review it.
