Removes various image filtering/mipmapping leftovers from pre-2.80 days. Code: removes all mipmap handling from ImBuf (which is about half of ImBuf struct size), removes now unused "sample procedural texture with mipmaps" code, now-unused FELINE filter, etc. The osatex parameter to various CPU texture sampling functions is never actually used, which means none of the mipmap code was ever executing. User visible part: there were settings on the legacy Texture data block (as used by Brushes etc.), under Sampling section: "MIP Map", "Gaussian Filter", "Filter Type", "Eccentricity", "Minimum Size" -- they had no effect anywhere, so they are gone, and what remains is only "Interpolation" and "Size". RNA / Python API part: removes the ImageTexture RNA properties corresponding to the above: filter_type, use_mipmap, use_mipmap_gauss, filter_lightprobes, filter_eccentricity, use_filter_size_min.
