[pktverify] add filter_ipv6_src() to PacketFilter class (#12444)

Browse Source 
This commit adds the filter_ipv6_src() method to the PacketFilter
class in the pktverify framework. This method improves the symmetry
of the filtering API, complementing the existing filter_ipv6_dst().

The new method is used to update several verification scripts in
tests/nexus, replacing manual lambda filters for IPv6 source
addresses with a cleaner and more readable API call.

Updated scripts:
- tests/nexus/verify_5_3_3.py
- tests/nexus/verify_5_3_7.py
- tests/nexus/verify_5_3_8.py
- tests/nexus/verify_5_3_10.py
