SL-19349 Fix for hang on bulk upload of materials, add bulk upload option to material selector, incidental decruft.

DRTVWR-559 Return to MD5 for LLUUID operations.  Existing LLUUID API implementations must not change, but may add "fast" variants where appropriate in the future.

SL-19293: Use Blinn-Phong texture transform as hint for texture animation direction on PBR materials

SL-19281 Unify handling of haze and gamma between fullbright and not and move haze back to sRGB color space to stay consistent with sky colors.  Also fix broken "roughness" stuck at 0.2.

SL-19277 Fix for fallback probe sometimes getting occluded and making void water dark after teleport.  Never default to having reflections off.

SL-19226 Reimplement water fresnel offset/scale, exposure balance for midday, adjust reflections off, and decruft depth buffer error correction shenanigans that are no longer used.

DRTVWR-559 Fix for occlusion culling going off the rails when settings change -- remove LLPipeline::resetVertexBuffers and add a sanity check to how long we wait for a query to be "available".

SL-18563

SL-19269: For PBR materials, apply texture animation independently of the underlying texture transform

SL-19265: Fix precision issue with texture transforms by moving transform matrix calculation into the shader

SL-19212 Resurrect glare and apply to PBR materials as well (and fix color mismatch in legacy alpha vs opaque).

SL-19228: Fix GLTF texture transform rotation and add UV debug (PBR only). See textureUtilV.glsl for UV coordinate comments

DRTVWR-559 Fix for irradiance maps going black at 128x128 radiance map resolution.  Improve radiance map anti-aliasing and default to 128x128 everywhere.

DRTVWR-559 Fix for stall in probe occlusion culling and fix for culled neighbors getting sampled (badly).

DRTVWR-559 WIP -- occlusion culling for reflection probes -- has a defect for objects close to the camera at some angles and leaks query objects, will follow up.

SL-19239 Day after three day quality pass - add ACES tone mapping to address "haziness" (and also fix banding in emissive materials)

SL-18927 Warn *before* destroying content, not after.  Followup from last commit -- immediately apply scale to sphere probes.
