Add MediaQueryData.navigationMode and allow controls to be focused when disabled. (#54919)
This adds a new navigationMode to the MediaQueryData that indicates how focusable controls should behave under different navigation modes, currently with two modes: NavigationMode.traditional, and NavigationMode.directional.

It may seem like focusing a disabled control is not desirable, but this is useful for user interfaces that use DPAD navigation because if a control gets disabled, losing focus is disruptive to the user, and it is difficult to control where the focus will end up unless it is done explicitly.

Flutter

Flutter is a new way to build high-performance, cross-platform mobile apps. Flutter is optimized for today's — and tomorrow's — mobile devices. We are focused on low-latency input and high frame rates on Android and iOS.
