[Arista]: Disable SA_EQUALS_DA trap on DNX LC SKUs (#17206)

Browse Source 
This change was submitted directly to 202205 but it's also needed in master and 202305 with SAI9.x
#13346

There has been a couple CSPs for this as well:
CS00012273013 - [7.1][J2, J2c+] Disable SA Equals DA trap on DNX
CS00012320965 - SAI9.2: iBGP doesn't work due to SA_EQUALS_DA trap

If SA_EQUALS_DA trap is enabled iBGP won't work as the Ethernet-IB0 ports are expected to get packets with SA==DA.

In the VOQ chassis design, for outgoing control plane packets, the packets goes the recycle port for routing, therefore the dmac of the packet should be the asic router mac. The source mac is assigned by the kernel, so it is also the asic router mac.
