qemu-doc: update deprecation section to use -nic and -netdev hubport
The deprecated SLIRP options -tftp, -bootp, -redir, -smb provide sample replacements that use "-net nic". Suggest "-nic" instead, since we finally have a path towards getting rid of "-net". For "-net vlan" the replacement involves hubport network devices, so mention that too.

@subsection -net vlan (since 2.9.0)
-The ``-net vlan=NN'' argument is partially replaced with the
-new ``-netdev'' argument. The remaining use cases will no
-longer be directly supported in QEMU.
+The ``-net vlan=NN'' argument was mostly used to attach separate
+network backends to different virtual NICs. This is the default
+behavior for ``-netdev'' and ``-nic''. You can connect multiple
+``-netdev'' and ``-nic'' devices to the same network using the
+"hubport" network backend, created with ``-netdev hubport,hubid=NN,...''
+and ``-nic hubport,hubid=NN''.
