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.

SwitchPreference and SwitchPreferenceCompat are both TwoStatePreference.
Using TwoStatePreference in Java will helps migration in the future.

Refactor SettingsContentObserver and rename it to
AccessibilitySettingsContentObserver. Besides, we register it to observe
follow typing feature preference value.
The reasons behind refactor:
1. We change callback signature due to the consistency for register it
by preference key, not by Uri.
2. We refactor the default preference key to a seperate method. Since
the default value is related to accessibility, we rename it with
accessibility prefix.
3. We can register different callback for difference collections of
preference keys.
Default preference keys: They existed in the previous constructor.
1. Settings.Secure.ACCESSIBILITY_ENABLED
2. Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES

There are 3 milestones in this feature.
1. Refactor the callbacks for Accessibility in WindowManagerInternal.
2. Implement this feature in such new architecture.
3. Implement the setting choice in preference page.
This CL is for the 3rd milestone.
We add a preference key "magnification_follow_typing" to access and
update the ACCESSIBILITY_MAGNIFICATION_FOLLOW_TYPING_ENABLED value
which controls its corresponding preference page UI.
