Create a debug screen for displaying all shared pref flags

[justtwago]

Created a screen for internal purposes to display and modify saved local flags. It's available on the debug settings screen

PS: I'm open to a better name for the screen 😄

---

To Test:

• Launch a debug app
• Go to Me -> Debug settings
• Open a dropdown menu on the toolbar and tap on All local flags
• Make sure you can see your locally saved boolean flags from shared prefs
• Modify any and make sure the new value is saved

Hey @justtwago

The changes look good to me, approving but not merging so that others can have a look

💡 Suggestion: Change the naming to Preferences or Shared Preferences.
