Re-upload (part of) a mesh's second UV buffer (uv2) — the twin of
updateMeshUvsfor dynamically re-generated geometry whose per-vertex uv2 payload changes each rebuild (e.g. a procedural batch that re-bakes per-vertex AO / gradient data). The uv2 attribute is vec2 (8 bytes/vertex). No-op if the mesh was created without uv2. Zero-allocation GPU upload only.
