refactor: Remove unused LogPrint

   useful for debugging and can reasonably be enabled on a production
   system (that has sufficient free storage space). They will be logged
   if the program is started with `-debug=category` or `-debug=1`.
-  Note that `LogPrint(BCLog::CATEGORY, fmt, params...)` is a deprecated
-  alias for `LogDebug`.
 
 - `LogInfo(fmt, params...)` should only be used rarely, e.g. for startup
   messages or for infrequent and important events such as a new block tip
