refactor(smudge): Replace custom doubly linked list with std::deque in W3DSmudge

[stephanmeesters]

• Replaces DLListClass usages in W3DSmudge with std::deque. std::deque was chosen instead of std::list because we only needed removals/insertions at the front/back (no splicing).
• Removes some unused functions to reduce the conversion work
• Replaces bookkeeping field m_usedSmudgeCount with the queue's size

Greptile Summary

Refactors smudge storage from intrusive doubly linked lists to standard deque-backed pointer queues.

• Removes DLNodeClass inheritance and unused individual-removal APIs.
• Derives the active smudge count directly from the queue size.
• Updates allocation-pool cleanup, reset, lookup, and render-batch traversal to use deque operations and iterators.

Confidence Score: 5/5

The PR appears safe to merge with no actionable regressions identified.

The deque conversion preserves ownership, ordering, reset behavior, and render-batch traversal, while the removed APIs have no surviving callers or interface dependencies.

Important Files Changed

Filename	Overview
Core/GameEngine/Include/GameClient/Smudge.h	Replaces intrusive-list types and node inheritance with deque aliases while preserving the public smudge-management contract used by current callers.
Core/GameEngine/Source/GameClient/System/Smudge.cpp	Converts pool ownership and traversal to explicit deque operations, removes unused APIs, and fixes free-smudge cleanup to pop from the correct queue.
Core/GameEngineDevice/Source/W3DDevice/GameClient/W3DSmudge.cpp	Converts both render passes and cross-batch resume state to deque iterators while preserving progress across hidden smudges, empty sets, and batch boundaries.
