Rename all RenderQueue enqueue function constants with RQ_ prefix for
consistency (e.g., DRAW_PIXEL -> RQ_DRAW_PIXEL). Add 20 new address
constants for helpers, pipeline functions, and the type 0xE enqueue.
Label 25 functions in Ghidra including 7 RQ helpers and 7 render
pipeline functions. Document complete render queue system in
docs/re-notes/render-queue.md.
Research findings:
- All 11 standalone enqueue functions identified (types 0-14 switch,
but types 3/7/10/12 have no standalone enqueue — inlined or unused)
- DDDisplay vtable drawing method map (12 slots at 0x2C-0x58)
- Render pipeline: RenderFrame -> GameRender -> RQ_RenderDrawingQueue
