left and right prop of TextInput should accept other than icons

I was going through `TextInput` props and saw that `left` prop only accepts below

> It can be either TextInput.Icon or TextInput.Affix

In material UI (MUI) react web version, start accepts `Icon` as well as other type of `React.ReactNode`

I was trying to do something like this

```js
console.log('Remove chip')}
style={{ marginRight: 4 }}
>
Apple

}
right={
loading ? (
} />
) : undefined
}
/>
```

I know there might be some workaround like wrapper pattern, Is it possible that RNP provides this feature internally ?

MUI --

I want to achieve something like this in terms of UI

Thanks

首先阅读 TextInput 的 prop 定义以及其左侧和右侧元素的实现。将当前对 TextInput.Icon 和 TextInput.Affix 的处理与所要求的 Chip 和 ActivityIndicator 示例进行比较。完成应意味着两个 prop 都支持示例中的非图标内容，同时保留现有支持的形式。
