开启多层FDanglingCheck::FGuard后,最内层的FGuard销毁会销毁所有的CapturedContainers和CapturedStructs（invalid TArray）

[lzj10]

开启多层FDanglingCheck::FGuard后，最内层的FGuard析构会销毁所有的CapturedContainers和CapturedStructs，导致外层的局部变量失效。
出现场景，委托回调到lua，在lua中创建umg，之后局部变量失效
复现方式
1、创建UTestClass,UTestClass2

#pragma once

#include "CoreMinimal.h"
#include "UObject/Object.h"
#include "TestClass1.generated.h"

/**
 * 
 */
UCLASS()
class GANGSTAR_API UTestClass1 : public UObject
{
	GENERATED_BODY()

public:

	UPROPERTY(BlueprintReadWrite)
	TArray<FString> TestArr;
};

#pragma once

#include "CoreMinimal.h"
#include "UnLuaInterface.h"
#include "UObject/Object.h"
#include "TestClass2.generated.h"

UCLASS(Blueprintable)
class GANGSTAR_API UTestClass2 : public UObject,public IUnLuaInterface
{
	GENERATED_BODY()

public:

	UFUNCTION(BlueprintCallable)
	void TestFun()
	{
		TestImpl();
	}

	UFUNCTION(BlueprintCallable)
	void TestFun2()
	{
		TestImp2();
	}

	UFUNCTION(BlueprintImplementableEvent)
	void TestImpl();

	UFUNCTION(BlueprintImplementableEvent)
	void TestImp2();

	virtual FString GetModuleName_Implementation() const override
	{
		return TEXT("Test2Impl");
	};
};

2、lua文件Test2Impl.lua

local Test2Impl = UnLua.Class()

---由于是重写函数，c++从FFunctionDesc::CallLuaInternal调用过来，有一层FGuard
function Test2Impl:TestImpl()
    local testObj = NewObject(UE.UTestClass1, GameInstance)
    local testRef = UnLua.Ref(testObj)
    local testArr = testObj.TestArr

    --testArr正常，可以打印出长度为0
    UnLua.Log("###########   Test arrptr callTest 1: " .. testArr:Length())

    --触发函数调用,由于TestFun2函数在c++中调用了TestImp2，触发了FFunctionDesc::CallLuaInternal
    --开启了新的FGuard，执行结束后FGuard析构testArr 被销毁
    self:TestFun2()

    --testArr报错失效
    UnLua.Log("###########   Test arrptr callTest 2 : " .. testArr:Length())
end

function Test2Impl:TestImp2()
    UnLua.Log("###########   TTest2Impl:TestImp2()")
end

return Test2Impl

3、在lua中创建UTestClass2 并调用TestFun,报错 局部变量testArr被销毁

local obj = NewObject(UE.UTestClass2, GameInstance)
obj:TestFun()
