WindowServer: Add WindowStack concept

Browse source 
This patch moves the window stack out of WindowManager and into its own
WindowStack class.

A WindowStack is an ordered list of windows with an optional highlight
window. The highlight window mechanism is used during Super+Tab window
switching to temporarily bring a window to the front.

This is mostly mechanical, just moving the code to its own class.
