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
