Init out struct parameters to prevent NullReferenceException

[UlyssesWu]

Reason:

InjectFix/Source/VSProj/Src/Core/StackOperation.cs

Lines 256 to 260 in 552da36

	internal static unsafe object ToObject(Value* evaluationStackBase, Value* evaluationStackPointer,
	object[] managedStack, Type type, VirtualMachine virtualMachine, bool valueTypeClone = true)
	{
	//未初始化的local引用可能作为out参数反射调用
	//TODO: 验证值类型out参数，对应参数位置是否可以是null？

Known issue, but never fixed😅

Test case:

        public struct TestStruct
        {
            public int a;
            public string b;
        }

        [Patch]
        public void TestOutStruct(out TestStruct ts)
        {
            ts.a = 114514;
            ts.b = "buggy IFix";
        }

        public void Awake() // must not be [Patch]ed
        {
            TestStruct ts;
            TestOutStruct(out ts);
        }
