Summary

Adds Mirror-on-Drop support for Tajo (Yuba/G202X): SAI TAM configuration/teardown, SDK punt-header parsing, Tajo-specific agent hw test validation, and improved MoD packet capture in shared stateless tests. Previously MoD worked on XGS/DNX but not on Tajo platforms.

Test Plan

Verified on Tajo hw G200 by running AgentMirrorOnDropStatelessTest (DefaultRouteDrop, MmuDrop, AclDrop) and AgentMirrorOnDropSrv6Test.Srv6Drops. All passed. Logs showed MoD packets captured and validated via TajoMirrorOnDropImpl (SDK punt header parse, drop reason codes, collector outer header). Pre-commit passed on all PR files.
