[LOGONUI] Make Logon UI compilable again (#4684) 
Logon UI was excluded from CMake build, probably for not being compliant
with 'warnings are errors' standard introduced at some point.
In the future, I would probably try to make Logon UI usable
alongside with the classic msgina interface.

- Add logonui back to CMakeLists
- Replace 'wcscpy_s' Vista+ function with StringCchCopyW
- Exclude some unused functions
