Introduce JERRY_ZSTR_ARG macro to avoid jerryx_print_string, jerryx_print_byte, jerry_port_print_byte, strlen (#4982)

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
