Blink WebTouchPoint stores its location as WebFloatPoint, instead of WebPoint.

This is the second of three patches converting WebTouchPoint to use
WebFloatPoint instead of WebPoint.

The first patch (https://codereview.chromium.org/140973005) allows
chromium to accept WebFloatPoint (it just casts all the floats to
ints).

The third patch (https://codereview.chromium.org/148453012/) will
clean up the chromium side.
