Windows: Add setting/CLI switch to enable IME during Secure Desktop. Fix Preferences tabs handling.

Browse Source 
Now it is possible to enable IME during Secure Desktop using a setting in Preferences or using /enableIME switch.
This helps solve issues with some IME that causes VeraCrypt to freeze when selecting keyfile while VeraCrypt secure desktop is active.
