Use ColorSpace to support various types of raw bitmaps. API Modifications: - Result Picture::load(uint32_t* data, uint32_t w, uint32_t h, bool premultiplied, bool copy = false) -> Result Picture::load(uint32_t* data, uint32_t w, uint32_t h, ColorSpace cs, bool copy = false) - Tvg_Result tvg_picture_load_raw(Tvg_Paint* paint, uint32_t *data, uint32_t w, uint32_t h, bool premultiplied, bool copy) -> Tvg_Result tvg_picture_load_raw(Tvg_Paint* paint, uint32_t *data, uint32_t w, uint32_t h, Tvg_Colorspace cs, bool copy) issue: https://github.com/thorvg/thorvg/issues/1372
