This patch makes it to spoof the pointer id into mouse pointer id
when resistfingerprinting is enabled. And we will only spoof for
content but not for chrome. Since we don't know the pointer id
beforehand, we have to cache the pointer id of the mouse interface when
it is activated. And use that pointer for the purpose of fingerprinting
resistance.

The pointerType field in the pointer event will reveal the details of
users' hardware; this is a fingerprinting vector. So, we would spoof all
types of pointer events into mouse type pointer events for protecting
users from browser fingerprinting when fingerprinting resistance is on.
In this patch, we would spoof the pointerType as well as other fields
that mouse pointer events don't support, like pressure, tiltX/Y and so
on when fingerprinting resistance is on.

We implement PointerEvent.getCoalescedEvents as
1. Clone the widget events we coalesced.
2. Convert them to dom::PointerEvent when user calls getCoalescedEvents.
