[nexus] add SRP-TC-6 for DNS name compression handling (#12765)
This commit adds the Nexus test case 1_3_SRP_TC_6 which verifies that the SRP server correctly handles SRP Updates both with and without DNS name compression, according to the Thread 1.3 test specification. The implementation includes: - tests/nexus/test_1_3_SRP_TC_6.cpp: Executes the test sequence by configuring a Thread Border Router (DUT), an End Device (ED), and an Infrastructure node (Eth). It uses SetDnsNameCompressionEnabled() to toggle name compression for SRP Updates. - tests/nexus/verify_1_3_SRP_TC_6.py: Performs automated verification of the captured traffic (PCAP), ensuring that SRP Updates, DNS queries, and mDNS responses are correctly formatted and contain the expected resource records. - Updating tests/nexus/CMakeLists.txt and tests/nexus/run_nexus_tests.sh to integrate the new test into the build and default test suite. The test ensures that the SRP server can successfully parse uncompressed names in SRP Updates and that subsequent DNS/mDNS discovery remains functional for both compressed and uncompressed registration formats.
