mlxsw: spectrum: mr: Support trap-and-forward routes
Add the support of trap-and-forward route action in the multicast routing offloading logic. A route will be set to trap-and-forward action if one (or more) of its output interfaces is not offload-able, i.e. does not have a valid Spectrum RIF. This way, a route with mixed output VIFs list, which contains both offload-able and un-offload-able devices can go through partial offloading in hardware, and the rest will be done in the kernel ipmr module.
