feat(traffic): Add SWB loopback line-speed traffic tool

Browse Source 
Blanton_Script/blanton_traffic_linespeed.sh V0.3.2 drives the whole
loopback traffic run from the DUT shell via bcmcmd, for both switch
boards (unit 0 and 1):

- init  : vlan remove 1 pbm=cd, then create/add the 108 loopback
          pairs (VLAN 30..137, cdN <-> cdN+32)
- clear : clear c
- show  : show c (raw)
- start : tx <count> length=<len> VLantag=<vid> per VLAN
- stop  : remove the pairs, optional --destroy
- ps    : port status of the cabled ports
- report: parse the show c MIB_TPOK/MIB_RPOK counters and lay them
          out one pair per block with a cross-check verdict
          (cdA.TX == cdB.RX and cdA.RX == cdB.TX), PASS green /
          FAIL red / NA yellow, --tolerance for snapshot skew,
          --tsv, --raw and -f <log> for offline analysis; the raw
          capture is kept under /tmp
- run   : ps -> init -> clear -> start -> report

Options -u/-c/-l/-p/-T/-d/-n and a sourceable function API, in the
style of the other blanton_*.sh tools. Command output matches the
former Tera Term macros byte for byte; report output matches
tools/bcm_mibpair_report_V1.1.0.py, added here as the off-box
equivalent, together with the raw bcmcmd command lists under tools/.

ScriptA sources the tool, ScriptB runs ps/init/clear/show/start and
drops stress_hhmd and stress_pcie, ScriptC stops the traffic and
prints the pair counter report.
