    [CONUTILS] Diverse improvements: start doxygenating and add some resource messsage
helper functions.
    - Start to doxygenate the library, focusing in great details on the
      functions of the "outstream" module.
    - Add a K32LoadStringEx function that expands (K32)LoadString by
      allowing a LanguageId parameter to be able to load strings from other
      languages than the current one.
    - Add "ConResMsg*" helper functions to be able to (format and) print
      message strings with inserts that come *NOT* from a message table (as
      usual) *BUT* from resource string tables.
      Will be helpful for CORE-14265 in particular.
    [CMD] Fix the call to ConMsgPrintfV().

+ * @brief   This library contains common functions used in many places inside
+ *          the ReactOS console utilities and the ReactOS Command-Line Interpreter.
+ *          Most of these functions are related with internationalisation and
+ *          the problem of correctly displaying Unicode text on the console.
+ *          Besides those, helpful functions for retrieving strings and messages
+ *          from application resources are provided, together with printf-like
+ *          functionality.
