tipc: add name table dump to new netlink api

Add TIPC_NL_NAME_TABLE_GET command to the new tipc netlink API.

This command supports dumping the name table of all nodes.

Netlink logical layout of name table response message:
-> name table
    -> publication
        -> type
        -> lower
        -> upper
        -> scope
        -> node
        -> ref
        -> key
