Add EscapeContext keybind (#15301)

Add EscapeContext keybind (#15301)

* 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.
