Meta: Improve UI navigation code abstraction

[SBiOSoftWhare]

Attack plan:

• Move navigation code from MasterTabBarController to TabBarCoordinator, see Create a root coordinator per legacy screen flows #3597
• Create a Coordinator for every root view controller of the tab bar, see Create a root coordinator per legacy screen flows #3597
• Create a Coordinator for RoomViewController, see Create a root coordinator per legacy screen flows #3597
• Move deep link management from LegacyAppDelegate to AppCoordinator and create a parser for deep link. Handle first Create a universal link parser #3595 then Improve deep link management #3600
• Move session management code from LegacyAppDelegate to a dedicated class, see Move Matrix sessions management in a dedicated class #3618
• Migrate AuthenticationViewController to Coordinator, see Create a root coordinator per legacy screen flows #3597
• Manage authentication flow management from MasterTabBarController to AppCoordinator, see Move Matrix sessions management in a dedicated class #3618
• For tab bar, use navigation controller at the right place and put one inside each tab, see View hierarchy: Do not embed UITabBarController inside UINavigationController #3086

Note: When moving navigation code or creating a Coordinator extract Storyboards from the main one, see #3596
