mlxsw: spectrum: Add multicast router traps and trap groups

Add three new traps needed for multicast routing:
 - PIM: Trap for PIM protocol control packets.
 - RPF: Trap for packets that fail the RPF check on a specific hardware
   route entry.
 - MULTICAST: Generic trap for multicast. It is used for routes that trap
   the packets to the CPU.

The RPF and MULTICAST traps have rate limiters as these traps may have
line-rate of packets trapped. The PIM trap has a rate limiter similarly to
other L3 control protocols. The rate limiters are implemented by adding
three new trap groups for the newly introduced traps.
