Fix outline rendering: cached DIP replay, disable depth for silhouettes

Browse Source

Switch from double-DIP (which corrupted WoW's GxDevice state) to cached
replay in EndScene. Cache draw params + GPU state (VB, IB, vertex decl,
VS, 256 VS constant registers) during the DIP hook, replay to silhouette
RT in EndScene before the JFA pipeline.

Remove D3D9 state blocks entirely — use comprehensive manual save/restore
of all modified state (render states, sampler states, shader constants,
COM objects with proper AddRef/Release).

Disable depth testing for all silhouette replay categories. By EndScene
the depth buffer has the full scene, so LESSEQUAL testing creates holes
in the silhouette wherever other models overlap — breaking the JFA
outline for targets and raid marks. Corpses already used ZENABLE=FALSE.

Add per-frame diagnostic counters (scan/classify counts by category)
logged via OutputDebugStringA for the first 20 active frames.

Clean up unused code: comAddRef, deviceCreateStateBlock, stateBlockApply.
