Using options in js runtime option list and delete stub compiler option. Add path check for stub compiler generation phase. Load stub file before loading of aot file. Add runtime option for optimization level configuration. Issue: https://gitee.com/openharmony/ark_js_runtime/issues/I557Q2 Signed-off-by: luochuhao <luochuhao@huawei.com> Change-Id: Ifbaa7a2dc4333310c62f1f8e230eefb7a2136ca5
