mlxsw: spectrum_router: Add support for VRFs
Allow port netdevs, LAG and VLAN devices stacked on top of these to be
enslaved to a VRF master device.
Upon enslavement, create a router interface (RIF) for the enslaved
netdev and associate it with a virtual router (VR) based on the VRF's
table ID.
If a RIF already exists for the netdev (f.e., due to the existence of an
IP address), then it's deleted and a new one is created with the
appropriate VR binding.
