…AUXILIARY, vertex inputs

Top-level descriptors (PIPELINE_STATE, MULTIVIEW, EXECUTION_MODEL, EXTENSIONS,
CLIP_DISTANCES / CULL_DISTANCES, DEPTH_LAYOUT). New input kinds: uniform_input
(UBO INPUTS), per-input sampler_config (WRAP / FILTER / COMPARE / MIPS),
audio_sampler_config. Storage / image / cubemap input extensions: PERSISTENT,
IS_ARRAY, GENERATE_MIPS, cube/3D textures. Geometry input AUXILIARY: storage +
sampled, persistent, is_uniform, depth companion, INDIRECT block. Per-pass:
LAYER, Z, FORMAT, PIPELINE_STATE override. OUTPUTS: LAYERS, DEPTH, FORMAT,
SAMPLES, CUBEMAP, GENERATE_MIPS, WIDTH/HEIGHT expressions. Vertex inputs:
REQUIRED, DEFAULT, SEMANTIC, INTERPOLATION (with auto-flat for int/bool
varyings).

Bug fixes: mat3/mat4 attribute slot count, TYPES struct emission in BOTH
stages, drop incorrect std430 padding heuristic that was breaking RawLight
stride.
