LibWeb: Implement WebDriver pointer action execution

Browse source 
This implements execution of the pointer up, pointer down, and pointer
move actions.

This isn't 100% complete. Pointer move actions are supposed to break
the move into iterations over the specified duration, which we currently
do not do.
