magic-boost: make availability observable

- This CL fixes an issue where Quick Answers search item is left in OS
  Settings.
- Make availability value observable. Availability value is unavailable
  until refresh tokens are loaded. Reading the value early after a login
  can return an incorrect value.
- Take `RefreshTokensLoadedBarrier` from `scalable_iph_factory_impl.cc`.
  ScalableIph code will be deleted later. Simply take it to anonymous
  namespace of magic boost code instead of extracting it to a file.

Fixed: b:383612536
Test: unit_tests
