#1748 enabled support for PFC-WD detection and restoration for cisco-8000 using the drop action handler.

In the above referenced PR, support was added for dropping the Tx traffic from the port/tc where PFC-WD is detected.

This issue is created to enable drop the Rx traffic on the port/tc where PFC-WD is detected.

Will open a PR against sonic-swss/202012 branch once internal testing is complete

patch for issue #1971 - enable Rx Drop handling for cisco-8000 (#2041)
a4c80c3 
What I did

Enables support for Rx traffic drop for a port/tc by applying the zero buffer profile
Changed class hierarchy so that default getHwCounters() function is used (since the Rx counter support is enabled)
Fixes a pfc-wd off by 1 detection in case of PFC-WD detection without traffic
Why I did it

enabling a missing functionality
leveraging sonic code as our sdk now implements the missing counter
fixes a bug
How I verified it
on a cisco-8000 router:

detected pfc-wd detection and restore happens within the (detection/restore-time + 1 poll interval) duration and that the changeset passes MSFT tests
Verified that when PFC-WD is detected, both Rx and Tx traffic for a port/tc is dropped and no forwarding happens
Details if related

this patch will need to be double committed to the 202012 branch along with #1942 , #1748 and #1962
