[BROWSEUI] Add status bar view state persistence (#5366)

- Use `HKCU\Software\Microsoft\Internet Explorer\Main\StatusBarOther` registry key for the setting persistence.
- Set its value to 1 when the status bar is visible, and to 0 when the status bar is hidden.
- Query it when the file browser is initialized to set the correct view state for the status bar.
- Set the default state of the status bar to hidden if the registry key does not exist, matching the behavior of Windows Server 2003.
