* Track window states: active, fullscreen and tabsintitlebar for each window
* Use toolbar.id and window state to store and retrieve values from cache
* Note: As each window has its own ToolbarIconColor object, the cache is not currently shared across windows
* inferFromText callers pass in a reason and associated value, which is used to update the state we track, and potentially clear out the cache
* Create new windows test directory for browser-window-specific tests like this
* Test for the ToolbarIconColor changes to avoid sync style flushes when windows activate/deactivate

TabsInTitlebar has various ifdefs to avoid shipping code that's not gonna be used on Linux. Instead of complicating the logic with AppConstants checks and shipping this extra code unecessarily on Linux, i've separated the code to a different file that can be replaced by a stub implementation.
