Zijie He 77b7a1da2d Tests for WindowFinder
This change adds several tests for WindowFinder implmenetations.
One of the tests uses ScreenDrawer to create a foreground window or console
window (on Windows) and ensures WindowFinder can return its window_id().
The other ensures WindowFinder always returns kNullWindowId if the |pos| is out
of the screens.
