pd commands: support PD console command srccaps
This allows servo querying DUT's srccap easier.
BUG=b:140256624
TEST=on servo_v4 (TCPMv1) and Asurada (TCPMv2) tested that
1. plug adapter `pd 0 srccaps` show the PDOs
2. unplug adapter `pd 0 srccaps` show nothing
sample output:
> pd 1 srccaps
0: 5000mV/3000mA
1: 9000mV/2000mA
2: 12000mV/1500mA
3: 3300mV-5900mV/3000mA
4: 3300mV-11000mV/2000mA
