    [EXPLORER] Show time and date when two lines are available in the taskbar clock area
(#5410)
    
    - Add registry key to show the time and date when two lines are available
      in the taskbar clock area.
    - Keep old behavior when `PreferDateOverWeekday` registry key in
      `HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced`
      is set to 0 or not present.
    
    When three or more lines are available, the clock will continue to show
    the time, day of the week, and the date. When only one line is visible,
    the clock will continue to only display the time.
