Memory Leak with Fetch

Description

I have encountered a memory leak issue when using the fetch function in my React Native application. The memory usage gradually increases over time in iOS, leading to performance degradation and potential crashes.

React Native Version

0.72.4

Steps to reproduce

1.	Create a React Native project with the necessary dependencies.
2.	Implement a screen or component that utilizes the fetch function to make API requests.
3.	Monitor the memory usage of the application over an extended period.
4.	Observe that the memory usage consistently increases during and after making multiple fetch requests.

minimal example:

首先，在 iOS 上使用 React Native 0.72.4 运行 https://github.com/clemensmol/rn-fetch-memoryleak 中的最小示例，并监控重复 fetch 请求期间的内存。跟踪请求行为，并比较运行复现程序前后的内存；当已解决所演示的内存增长问题，且复现不再显示内存泄漏时，即视为完成。
