lib, vtysh, topotests: fix 'show ip[v6] access-list ... json' formatting

Similarly to recently fixed 'show ip[v6] prefix-list ...' - PR#15750,
json output is not valid for 'show ip[v6] access-list ... json' commands,
as it goes through all the running daemons and for each one it calls
'filter_show' creating a new json object. To aggreagate the output
and create a valid json that can later be parsed, the commands were
moved to vtysh and formatted accordingly
