NVN2 image handles the translator couldn't trace, found on The Duskbloods network test (and needed by Persona 3 Reload):

• host/nvn: an image the shader picks from c2's table at run time binds as a 32-entry slot array, where element k is image slot k (profile key tex_dyn_slots, as for textures).
• chain/translator: an image whose handle the shader loads from memory (the fog volume, GXFogVolume_*, reads its 3D image handle from storage buffer 0) can't be a slot array, because the index is the image ID itself. It now indexes an image pool by ID: a new reflection kind, img_pool, gets a table filled by the replay with the bound images (the write sink elsewhere). Without it the fog volume was never written and the world drew black behind the HUD. Covered by test_dmsh_pool_arrays.py.
• chain: dmsh_xlate rebuilt (native tools, arm64 + x86_64), with the lock and the chain header.

Rebased on main: SULD / SUST through a register, the first commit here before, is in main already (4032a11), so it is dropped.
