Jonathan Hui 05ad9803d8 [nexus] add 1.4 PIC-TC-1 test for DHCPv6-PD and DNS (#12859 )

This commit adds a new Nexus test that implements the test
specification in test-1-4-PIC-TC-1.md. The test verifies Border
Router functionality including:
- DHCPv6-PD client to obtain OMR prefix
- Advertising route to OMR prefix on AIL (Stub Router)
- DNS recursive resolver for public internet addresses
- Connectivity (ICMPv6, UDP, TCP/HTTP) to internet and local servers

New files:
- tests/nexus/test_1_4_PIC_TC_1.cpp: C++ test execution
- tests/nexus/verify_1_4_PIC_TC_1.py: Python pcap verification

Nexus platform enhancements:
- Enabled DHCPv6-PD client in openthread-core-nexus-config.h
- Implemented DHCPv6-PD platform APIs in nexus_infra_if.cpp
- Added RDNSS option to RA in nexus_infra_if.cpp
- Improved packet delivery on infrastructure interface in nexus_core.cpp
- Fixed upstream DNS query matching in nexus_dns.cpp

Description

TCPlp is a full-scale TCP stack for low-power wireless networks and resource-constrained embedded systems. It is designed to support performant and efficient TCP operation over IEEE 802.15.4 networks. It is based on the TCP stack in the FreeBSD operating system.

TCPlp is a software artifact that accompanies an NSDI 2020 paper:

Sam Kumar, Michael P Andersen, Hyung-Sin Kim, and David E. Culler. Performant TCP for Low-Power Wireless Networks. NSDI 2020.
