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.

To move the preference to the upper layer, we extract all logics
to its controller.
We move all tests to the test files and add server tests to
verify the behaviour of edit shortcut dialog.
