Set TextInput selection correctly when attached to window in Android (#46948)

Summary:
On Android, when `ReactEditText` is attached to window, `setTextIsSelectable` moves the caret to the beginning, so we need to restore the selection.

This is similar to what we did in https://github.com/facebook/react-native/pull/17851.

Fixes https://github.com/facebook/react-native/issues/46943

## Changelog:

[ANDROID] [FIXED] - Fix TextInput caret moving to the beginning when attached to window

Pull Request resolved: https://github.com/facebook/react-native/pull/46948

Test Plan:
Code to reproduce in RNTester:

```TSX
import type {RNTesterModuleExample} from '../../types/RNTesterTypes';
import {TextInput} from 'react-native';
import {useEffect, useRef} from 'react';

function Playground() {
  const input = useRef(null);
  useEffect(() => { setTimeout(() => input.current?.focus(), 1000); }, []);
  return <TextInput ref={input} value='1.00' selection={{start: 4, end: 4}} />;
}

export default ({
  title: 'Playground',
  name: 'playground',
  render: (): React.Node => <Playground />,
}: RNTesterModuleExample);
```
