Simplified parameters and ensured proper backend engine initialization by using reference checking through canvas instances. C++ API Modification: - Result Initializer::init(uint32_t threads, CanvasEngine engine) -> Result Initializer::init(uint32_t threads) - Result Initializer::term(CanvasEngine engine) -> Result Initializer::term() C API Modification: - Tvg_Result tvg_engine_init(Tvg_Engine engine_method, unsigned threads) -> Tvg_Result tvg_engine_init(unsigned threads); - Tvg_Result tvg_engine_term(Tvg_Engine engine_method) -> Tvg_Result tvg_engine_term() issue: https://github.com/thorvg/thorvg/issues/3116
