Exposed unprefixed Touch.rotationAngle to web.

Exposed unprefixed Touch.rotationAngle to web.

Intent to Implement and Ship:
https://groups.google.com/a/chromium.org/d/msg/blink-dev/KrokGpRH058/rQdIrSK5HM8J

We have the prefixed version (webkitRotationAngle) available since M39.
We will deprecate & eventually remove the prefixed versions of
rotationAngle and three other attributes (radisuX, radiusY & force)
afterwards.

LGTM, but wait to land until the blink-dev thread has one more LGTM. I started
linux_blink_rel, which I expect will fail on webexposed tests which you'll also
need to update.
