serial: Implement serial_flush() function for console flush() fallback
Like in all other console functions, implement also serial_flush() function as a fallback int console flush() function. Flush support is available only when config option CONSOLE_FLUSH_SUPPORT is enabled. So when it is disabled then provides just empty static inline function serial_flush().
