[BlackBerry] Disable WebCore::EventHandler synthesized mouse events during touch scrolling

[Antonio Gomes]

++++++++++++++++++++++++++++++++++++
FROM PRzilla:

I was looking at some odd pattern and discovered that the WebCore::EventHandler
will periodically synthesize mouse events while you scroll. On the desktop, the
mouse cursor remains still while you scroll using mouse wheel, so this seems
correct (the.cursor is moving relative to the page while scrolling, so mouse
move events are in order). But for touch scrolling it seems not only a waste of
battery but also completely wrong, because your finger does not move relative
to the page during touch scrolling, and the synthesized events have the wrong
position.

Instead of doesDeviceSupportMouse you can just do deviceSupportsMouse.
