[BROWSEUI] Add locked toolbar state persistence (#5350)

Store the state of the explorer toolbar, locked or unlocked, in the proper
    registry location and set the proper toolbar state when initialized.

CORE-9094

- Set `HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Toolbar\Locked`
      to 1 when the explorer toolbar is locked, 0 when the toolbar is unlocked.
    - Query `HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Toolbar\Locked`
      when the toolbar is initialized to set the correct locked state.
    - Set the default state of the toolbar to locked if the registry key does not
      exist, matching the behavior of Windows Server 2003.
