Hermès Bélusca-Maïto 1499e7ef53 [MSGINA] Improve Security and Shutdown dialog features (#8372) 
- Respect system policies for showing or hiding:

  * Security dialog "Lock Workstation", "Log Off", "Shut Down",
    "Change Password", "Task Manager" buttons;

  * "Log Off" entry in the Shutdown dialog;

- Disable the "Shut Down" Security dialog button, and the "Stand by",
  "Shut down" entries in the Shutdown dialog, if the logged user
  doesn't have the SeShutdownPrivilege.

- Add other missing `WLX_SHUTDOWN_STATE_*` shutdown flags that are
  supported by Windows.

- Improve the retrieval of shutdown options to be displayed in the
  "Shut Down" dialog. In particular, don't hardcode any sort of
  defaults, but let them come from what the user can do (Is logoff
  allowed? Does (s)he have the rights to shutdown/reboot? etc.).
  If no shutdown options are available, then simply don't display
  the dialog!

- Don't hardcode the default selected shutdown option. Either it comes
  from the user's registry and is valid (i.e. corresponds to an existing
  shutdown option in the dialog), otherwise, fall back to the first
  option in the dialog.

  In particular this means:
  * when opening the "Shut Down" dialog from the C-A-D Security
    dialog, by default we will select the "Log Off" option, or
    whatever the user last selected;
  * when opening the dialog from the "Turn Off" Start Menu item, default
    to the "Shut down" option, or whatever the user last selected.
  * when opening the dialog from the C-A-D "Log On" dialog (no user
    is logged in), the "Shut down" option will also be selected, or
    whatever the system operator last selected.

- For the shell-invokable `ShellShutdownDialog()` function, implement
  support for using a custom display user name, or the one in the
  `"Logon User Name"` registry value saved by `WlxActivateUserShell()`.
  Plus, the 3rd parameter specifies the list of shutdown options to
  *exclude* from the options list.
