Describe the bug
通过GetCustomAttributes获取Attribute，ILRuntime与预期结果不一致

To Reproduce

    [AttributeUsage(AttributeTargets.Class,AllowMultiple = true)]
    public class TestSystemAttribute:Attribute
    {
        public List<int> KeyCode { get; }


        public TestSystemAttribute(int[] keyCode)
        {
            this.KeyCode = new List<int>(keyCode) ;
        }
    }
    [AttributeUsage(AttributeTargets.Class,AllowMultiple = true)]
    public class TestSystem2Attribute:Attribute
    {
        public int[] KeyCode { get; }


        public TestSystem2Attribute(int[] keyCode)
        {
            this.KeyCode = keyCode;
        }
    }
    [TestSystem2(new []{1,2})]
    [TestSystem(new []{1,2})]
    public class Test
    {
        
    }

    public class AttributeTest
    {
        public static void TestRun()
        {
            var attrs = typeof (Test).GetCustomAttributes(typeof (TestSystemAttribute), false);

            Console.WriteLine(attrs.Length);// attrs.Length=0,此处该为1才对
            
            var attr2s= typeof (Test).GetCustomAttributes(typeof (TestSystem2Attribute), false);
            foreach (TestSystem2Attribute attr in attr2s)
            {
                Console.WriteLine(attr.KeyCode[0]);//IL_0078: ldelem.i4  
            }
        }
    }

Expected behavior
执行TestRun

你IL2CPP用GetCustomAttributes不报错吗

ILRuntime域里使用，不在主工程
