Initial setup ready for PIN/Biometric app lock.

[pixlwave]

The PR lays the initial groundwork for adding PIN/biometric unlock to the app. It makes the following changes:

• Adds a WindowManager which can switch between the main window and an alternate window.
  • Additionally includes an overlay window on the main window which we can use for global user indicators in the future.
• Adds a AppLockFlowCoordinator and placeholder AppLockScreen.
• Displays this flow in the alternate window when the app is backgrounded (placeholder view) and foregrounded (app lock screen).
• Adds a feature flag for the flow.
