Unframed display mode for Isolated Web Apps

Unframed display mode allows [Isolated Web Apps](https://chromeos.dev/en/web/isolated-web-apps) to occupy the entire browser window, which optimizes the workspace available. By removing standard window borders and title bars, developers can implement unique user experiences with branding and menu hierarchies that match the look-and-feel of native applications. Administrators can manage this feature with existing policies for window management: - [DefaultWindowManagementSetting](https://chromeenterprise.google/policies/#DefaultWindowManagementSetting) configures the default state for the window management for all apps. The policies below can override this default. - [WindowManagementAllowedForUrls](https://chromeenterprise.google/policies/#WindowManagementAllowedForUrls) allows IWAs with specified origins to enter unframed mode without any user interaction. - [WindowManagementBlockedForUrls](https://chromeenterprise.google/policies/#WindowManagementBlockedForUrls) blocks unframed mode for IWAs with specified origins, forcing Chrome to fallback to other available display modes.
