Issue description

该方法的签名为 public readPixels (x?: number, y?: number, width?: number, height?: number, buffer?: Uint8Array): Uint8Array | null https://github.com/cocos/cocos-engine/blob/d7aae745748dd132281b93c86d0bb0d778c8a9ad/cocos/asset/assets/render-texture.ts#L227

如果这样写：

const buffer = new Uint8Array(4)
texture.readPixels(0,0,1,1, buffer)

那么在浏览器环境下，buffer可以获取到像素值，但是在原生（ios、android）环境下，buffer的值不变。
