servo_v4/pd: support more source voltage to DUT
usbc_action support new subcommand chg which limits the max voltage
of PDOs.
Also, serov_v4 provides more PDOs to the DUT if the adapter supports it,
besides 5, 12, 20V.
BRANCH=servo_v4
BUG=b:140256624
TEST=see servo_v4 provides various kinds of SrcCap to DUT
