This fixes the initial value of FocusManager.highlightMode so that it gets initialized correctly on desktop platforms.

My recent update of this code (#52990) broke things so that the highlight mode never changed from the initial default of touch, which meant that focus highlights didn't show unless you set FocusManager.highlightStrategy to something (even automatic, the default: setting it caused the mode to be updated).
