ref-filter: introduce format_ref_array_item()
To allow column display, we will need to first render the output in a string list to allow print_columns() to compute the proper size of each column before starting the actual output. Introduce the function format_ref_array_item() that does the formatting of a ref_array_item to an strbuf. show_ref_array_item() is kept as a convenience wrapper around it which obtains the strbuf and prints it the standard output.
