Cocoa : correctly handle late events sent after window deactivate

Cocoa can still send events (tagged with the correct NSWindow handle) after having sent the window deactivate event.
This caused these events being discarded as there was no active window for GHOST_WindowManager.

Fix is to use this NSWindow handle to retrieve the target window and correctly push the event.

E.g. of effects of this bug: OSKey modifier stuck after having invoked Spotlight through its shortcut (Cmd + Space). This gave the impression the Blender window has not got focus back for the keyboard.

Ton, can you confirm if this fixes the "Cocoa window loses focus permanently on using Spotlight" issue you found ?
