[winpr,wlog] Add specialized text log functions

Browse Source 
The generic WLog_PrintMessage(VA) functions lack proper checks of the
supplied format strings.
Add WLog_PrintTextMessage(VA) functions that do compile time checks of
supplied format strings to uncover usage errors early and use them in
the logger macros.
