Various fixes to UV2 unwrapping and the GPU lightmapper. Listed here for context in case of git blame/bisect: * Fix UV2 unwrapping on import, also cleaned up the unwrap cache code. * Fix saving of RGBA images in EXR format. * Fixes to the GPU lightmapper: - Added padding between atlas elements, avoids bleeding. - Remove old SDF generation code. - Fix baked attenuation for Omni/Spot lights. - Fix baking of material properties onto UV2 (wireframe was wrongly used before). - Disable statically baked lights for objects that have a lightmap texture to avoid applying the same light twice. - Fix lightmap pairing in RendererSceneCull. - Fix UV2 array generated from `RenderingServer::mesh_surface_get_arrays()`. - Port autoexposure fix for OIDN from 3.x. - Save debug textures as EXR when using floating point format.
