9402 Batched Compression

[Rezmason]

Summary

( Charlie and Jeremy's first big feature!✨ )

• The model transform properties panel now has a batch compression checkbox; when checked, compressed GLBs with texture size 2048 (LOD_0), 1024 (LOD_1) and 512 (LOD_2) are generated alongside the original file. (The selected model and the original GLTF/GLB are unchanged.)
• All this functionality is also now available when right-clicking a model in the file browser and choosing "Compress".
