sonic-net#18033) What is the motivation for this PR? Adds more reliable PFC storm generation for interfaces connected to Arista fanout devices How did you do it? How did you verify/test it? Ran sonic-mgmt pfcwd tests on testbed with Arista fanout switches of the listed SKUs running EOS. Ran the pfc_gen script manually on Arista switches running Sonic.

Description of PR
NOTE: This is a duplicate of #17971, as @veronica-arista is away.
Add a pfc_gen script for Arista fanout devices to generate pfc pause frames by setting PFC backpressure status in hardware. Enable the storm generation to use this script on interfaces that are connected to Arista fanout devices running EOS or Sonic. Currently supports the following Arista devices:
Arista-7060X6
Arista-7060DX5
Arista-7060PX5
Arista-7060CX
Arista-7260CX3
Arista-7260QX3
This is implemented on top of PR #15594

How did you do it?
How did you verify/test it?
Ran sonic-mgmt pfcwd tests on testbed with Arista fanout switches of the listed SKUs running EOS.
Ran the pfc_gen script manually on Arista switches running Sonic.
Any platform specific information?
Supported testbed topology if it's a new test case?
