* Add EscapeContext
Escape context input closes windows if there are any open. If there are not any windows it opens the game menu.
* Add fluent for Escape Context
* Move EngineContext keybind to content
* Readd WindowCloseAll
* Fix EscapeContext not opening the game menu after using WindowCloseAll
WindowCloseAll does not clear the CloseRecentWindowUIController.recentlyInteractedWindows, which caused HasClosableWindow to return true because the list still had items.
Changed HasClosableWindow to check if windows in the list are still open and clear them if they aren't.
* Clean up EscapeContextUIController
