DXT5 RGBA8 export

[Flynsarmy]

Terrain3D expects textures to be in DXT5 RGBA8 format. Could we get an option to export our generated material as a texture file in this format?

Godot can't write DDS files or perform VRAM compression in exported projects, so this will require writing a custom exporter in GDExtension, likely by integrating libsquish.

That said, you can give Terrain3D PNG files and it'll work too (albeit with slower importing).
