Add navbar magnification to critical accessibility check

If a user enables navbar magnification on their new device and the
setting was disabled on their old device, we don't want to overwrite
this setting and disable it on their new device during d2d restore.

Bug: 79189332
Test: 1) atest SettingsHelperRestoreTest
2) manual:
- Source device setting off -> target device turns setting on in SUW
-> d2d restore does not overwrite
- Source device setting on -> target device does not turn setting on
in SUW -> d2d restores setting properly
