Signed-off-by: bingwang <bingwang@microsoft.com>

This PR is to add two extra lossless queues for bounced back traffic.
HLD sonic-net/SONiC#950

SKUs include

Arista-7260CX3-Q64

How I did it
Update the buffers.json.j2 template and buffers_config.j2 template to generate new BUFFER_QUEUE table.

For T1 devices, queue 2 and queue 6 are set as lossless queues on T0 facing ports.
For T0 devices, queue 2 and queue 6 are set as lossless queues on T1 facing ports.
Queue 7 is added as a new lossy queue as DSCP 48 is mapped to TC 7, and then mapped into Queue 7

How to verify it
Verified by UT
Verified by coping the new template and generate buffer config with sonic-cfggen
