sfc: support TC left-hand-side rules on foreign netdevs
Allow a tunnel netdevice (such as a vxlan) to offload conntrack lookups,
in much the same way as efx netdevs.
To ensure this rule does not overlap with other tunnel rules on the same
sip,dip,dport tuple, register a pseudo encap match of a new type
(EFX_TC_EM_PSEUDO_OR), which unlike PSEUDO_MASK may only be referenced
once (because an actual Outer Rule in hardware exists, although its
fw_id is not recorded in the encap match entry).
