Replace usage of jerryx_print_byte, jerryx_print_string with jerryx_print_buffer. As we now have JERRY_ZSTR_ARG, so we can take advantage of it With this, the jerry_port_print_byte port api won't need any more this reduced the port api surface JerryScript-DCO-1.0-Signed-off-by: Yonggang Luo luoyonggang@gmail.com
