This commit introduces the packet verification (PV) framework for certification tests. - Add packet verification framework code - Implement packet verification for cert 5.1.7 as a minimal example. There will be more 1.1/1.2 tests with PV submitted in the future. - Download pre-built thread-wireshark binaries from openthread/wireshark/releases for packet dissecting (used by pyshark) - Added a Github Action job for Packet Verification
