WL#11678: Logging services: Add unique error-ids to the messages logged using error_log_printf()

Affects: Server-8.0   —   Status: Complete

Following methods uses error_log_printf() internally to log the error  
message,                                                              
                                                                      
  *) my_message_local                                                 
  *) my_getopt_error_reporter                                         
  *) my_charset_error_reporter                                        
  *) Query_log_table_intact::report_error                             
  *) Component_db_intact::report_error                                
  *) sql_plugin.cc: report_error()                                        
                                                                      
All the error messages logged with these methods gets the same error-id
"ER_LOG_PRINTF_MSG".                                                  
                                                                      
Goal of this WL is to log all those error messages with the unique    
error-id.
