WindowServer: Don't start a drag and drop unless holding Primary mouse

Browse source 
Adds a member to record the last processed mouse buttons. If they
do not include MouseButton::Primary, return early before creating
a new drag and drop client. This fixes race conditions in which
MouseUp events canceling or completing a drop could be swallowed
by Overlay creation or postponed by an executing DragOperation,
leaving the operation in limbo.
