This CL avoids refreshing DisplayInfo when the display is not freeform.
As notifyConfigChange() is expensive, we want to minimize the call.
Note: enterDesktopByDefaultOnFreeformDisplay only checks the flag state
but showLockedTaskbarOnHome can check if the display is freeform in
addition to the flag state.
Flag: com.android.window.flags.enter_desktop_by_default_on_freeform_displays
Test: TaplTestsLockedTaskbar
