Refactor ID definition and callSignature initialization mechanism of runtime stub, optimizer stub and bytecode handler stub, reduce amount and complexity of macro used in calling those stubs. Add stubDes struct to classify stubs both in AOT file generation phase and AOT file loading phase. Fix some circular dependency problems in including header files. Fix certain inline function declaration and definition format problems, which could lead to compiling errors. Issue: https://gitee.com/openharmony/ark_js_runtime/issues/I4VMLD?from=project-issue Test: stubTest(unit test), richards with asm interpreter enabled Signed-off-by: luochuhao <luochuhao@huawei.com> Change-Id: Ibd5fcd963347b97f8dec227f3245d2064463b0b0
