TextInput keyboard opens when scroll long text

### Current behaviour

When `TextInput` contains long text, the text can scroll. But when the text scrolls, the Keyboard automatically pops up and scroll to the cursor position.
### Expected behaviour
The keyboard only open if user want to edit the text. When the user wants to reread the entered text, do not open the Keyboard to block the view and do not automatically scroll to the cursor position.
### How to reproduce?
```typescript
const [prompt, setPrompt] = useState('a very long text')

}
mode="flat"
clearButtonMode="always"
multiline
blurOnSubmit={true}
value={prompt}
style={{
flex: 1,
backgroundColor: undefined,
}}
onChangeText={(t) => {
setPrompt(t)
}}
returnKeyType="done"
collapsable
outlineStyle={{
borderRadius: 20,
borderWidth: 0,
borderBottomWidth: 0,
backgroundColor: undefined
}}
contentStyle={{
marginTop: 5,
borderBottomWidth: 0,
}}
underlineStyle={{
height: 0
}}
autoFocus={false}
focusable={false}
// showSoftInputOnFocus={false}
placeholder={'Enter your text'}
/>
```

从 React Native Paper TextInput 的实现及其焦点、滚动和键盘行为入手；issue 未指定源文件或测试。先在 iOS 上复现多行长文本示例，然后验证滚动以重新阅读文本时既不会打开键盘，也不会将光标移入可视区域，同时编辑仍然正常工作。
