As b/328787031, we make the MagnificationAlwaysOnPreferenceController observe the magnification capabilities then update the preference enabled state. Therefore, when changing the capabilities to window mode only, the preference will become unavailable.
We use the bug-fix flag to verify the fix with rollout process.

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.

Hide behind feature flag so no one sees the preference unless its enabled.
Defaults to enabled.
