iface_namemode: add new port role of Dpc

[yenlu-keith]

Description of PR

this testcase (iface_namingmode/test_iface_namingmode.py::TestShowQueue::test_show_queue_counters) is
to compare below 2 fields matching when alias mode is enabled.

(From DUT)
admin@MtFuji-dut:/etc/sonic$ grep -A 200 "BUFFER_QUEUE" config_db.json | grep -E "Ethernet240"

"Ethernet240|0-2": {
"Ethernet240|3-4": {
"Ethernet240|5-7": {

(TestCase gets from port_config.ini)

Approach

Test Case: add this solution and rerun
also, u can refer to yang module

Found the yang https://github.com/sonic-net/sonic-buildimage/blob/master/src/sonic-yang-models/yang-models/sonic-port.yang#L184

What is the motivation for this PR?

How did you verify/test it?

rerun this testcase and add current solution

Any platform specific information?
