feat(ttl): Take a SerDes DSC dump in Script A and Script C
Script A scans just before 'show uptime', Script C just before the NVMe
error info, so the pair brackets the soak:
./Blanton_Script/bcm_dsc_scan.sh -f blanton_dsc_ScriptA.log -F
./Blanton_Script/bcm_dsc_scan.sh -f blanton_dsc_ScriptC.log -F
Neither name carries %u, so the scan inserts _u0 / _u1 itself and unit 1
cannot overwrite unit 0 - that is where the four file names Script C
copies to /host/hw-eval/jobs come from. The scan already copies its own
output there; the explicit cp lines are a second pass, so a copy that
fails inside the scan still leaves the data on the USB stick.
Also removed the commented-out 100G PRBS call sites from all three
macros, along with a duplicated commented 100G port status block in
Script A and the stale bmc_monitor_ddr.sh block in Script C. They had
been dead since bring-up. port_prbs_monitor.sh still ships and still
runs by hand.
Script A's header goes to V1.1.9 and its Version History covers all of
the above, including the note that both new scripts are recorded 100644
and need chmod +x on the DUT.
