chore(magnification): remove onResume overrides for controllers in ToggleScreenMagnificationPreferenceFragment

Browse Source 
As b/186731461, so far MagnificationModePreferenceController and other
magnification preference controllers are only used in
ToggleScreenMagnificationPreferenceFragment, which is DashboardFragment.
Since DashboardFragment already updates preference state in its
onResume, so we can remove the onResume overrides in those controllers.
Besides, we can also remove the LifeCycle dependency for the controllers
since it's not used anymore.

Bug: 186731461
Flag: NA
Test: manually
      atest ToggleScreenMagnificationPreferenceFragmentTest
      atest MagnificationAlwaysOnPreferenceControllerTest
      atest MagnificationFollowTypingPreferenceControllerTest
      atest MagnificationJoystickPreferenceControllerTest
      atest MagnificationModePreferenceControllerTest
