qcacmn: Dptrace enhancements

Ver a proveniência 
* Log EAPOL, ARP, DHCP, MGMT, ROAM Events, ICMP, Data packets,
  TX-Completions by default.
* Set default verbosity as low (existing is high)
* Throttle ICMP and Data packets if threshold exceeds.
* Enable live mode by default. Added ini entry to disable
  it and configure high throughput thresh - gDptraceConfig
* Log only SA and DA for proto packets (and not 32 bytes)
* Format prints to fit in 1 line.
