[PATCH 2/4] ref-filter: provide ref_flags to pretty_print_ref()

["ZheNing Hu via GitGitGadget" <gitgitgadget@gmail.com>]

From: ZheNing Hu <adlternative@gmail.com>

pretty_print_ref() creates a ref_item through new_ref_array_item(),
but such ref_item does not set its flag member, this means that %(symref)
will not be processed in populate_value().

So provide ref_flags parameter to pretty_print_ref() and verify_tag().
pretty_print_ref() has two callers: cmd_verify_tag(), verify_tag(),
let for_each_tag_name() use read_ref_full() instread of read_ref() to
generate the ref_flags and pass to pretty_print_ref(); However,
cmd_verify_tag() needs to be modified later to support providing ref_flags
to pretty_print_ref().

At the same time, let verify_tag() pass "ref" instread of "name" to
gpg_verify_tag() and pretty_print_ref(), which can help pretty_print_ref
get fullref name.
