Support multi touch on Windows 8 AURA and ASH.
The touch events coming in from desktop chrome AURA and ASH have hardcoded touch ids
which breaks the gesture recognizer as it is unable to figure out that multiple touch points
are involved.
Fix on desktop Chrome AURA is to use the OS generated touch id mapped to the gesture recognizer range.
For ASH Windows 8 we pass in the mapped touch ids from the metro driver in the touch IPC messages.
