Turn the UnifiedPointerCapture flag on

This CL turn on the UnifiedPointerCaptureInBlink flag.
It does not need an 'intent' as it's only minor behavior change, more
like bug fixing.

The behavior changing is:
1. Fix setPointerCapture to an element in outer frame and move
mouse cursor to inner frame, event will sending to the capture
element correctly instead of send to inner frame
2. Reduce the mouse event hit test count when mouse dragging in
same origin iframe.
