mlxsw: spectrum_qdisc: Offload RED qevent mark

Browse Source 
The RED "mark" qevent can be offloaded under similar conditions as the RED
"early_drop" qevent. Therefore recognize its binding type in the
TC_SETUP_BLOCK handler and translate to the right SPAN trigger, with the
right set of supported actions.
