[MSGINA] Convert shutdown/logoff boxes back to modal dialog boxes (#5114)

Browse source 
- Convert all modeless dialog boxes back to modal dialog boxes.
- Use WM_TIMER to detect SHIFT key press instead, as you can't
  directly intercept messages on modal dialog boxes.
- Remove some unused functions.

Fixes explorer crash on shutdown cancel. CORE-17749
