This change will enable the logging system to handle printk() calls by default if printk support is enabled, which improves output resiliency when logging, mcumgr and printk calls are used. Will disable keep LOG_PRINTK disabled for tests which are not using the new API as moving to LOG_PRINTK causes test data to be output to a different UART in the old test system.
