Store and expose hidden profiles

[carlos-zamora]

Summary of the Pull Request

This PR replaces CascadiaSettings::_profiles with...

• _allProfiles: the list of all available profiles in the settings model (i.e. settings.json, dynamic profiles, etc...)
• _activeProfiles: the list of all non-hidden profiles (used for the new tab dropdown)

References

#8018: maintaining a list of all profiles allows us to serialize hidden profiles
#1564: Settings UI can link to AllProfiles() instead of ActiveProfiles() to expose hidden profiles
