TextLayout: take full width if text wrapped (#47435)

Summary:
### Problem
The calculated width for a multiline text is based on the longest line. However it does not account for text that wraps.

**Example** if numberOfLines=1 and the text wraps

```
+---------------------------+
This is a long text that
will wrap
+---------------------------+
```

The TextView will render
```
+---------------------------+
This is a long text t...
+---------------------------+
```

because the `calculatedWidth` took the width of the first line.

Also see #41770 (comment) for additional context.

### Solution

If the text wraps, take the whole width.

```
+---------------------------+
This is a long text that w...
+---------------------------+
```

Fixes #39722
Fixes facebook/yoga#1730

## Changelog:

[GENERAL] [FIXED] - Fix text not taking full width

Pull Request resolved: #47435

Test Plan:
```tsx
        <Text
          numberOfLines={1}
          style={{
            backgroundColor: 'red',
            alignSelf: 'flex-start',
            color: 'white',
            fontSize: 34,
          }}>
          {'This is a long text that will wrap.'}
        </Text>
        <Text
          numberOfLines={3}
          style={{
            backgroundColor: 'red',
            alignSelf: 'flex-start',
            color: 'white',
            fontSize: 34,
          }}>
          {
            '1\n\ntest\nThis is a long text that will wrap.This is a long text that will wrap.This is a long text that will wrap.\n'
          }
        </Text>
        <Text
          numberOfLines={3}
          style={{
            backgroundColor: 'red',
            alignSelf: 'flex-start',
            color: 'white',
            fontSize: 34,
          }}>
          {
            '1\n\nThis is a long text that will wrap.This is a long text that will wrap.This is a long text that will wrap.\n'
          }
        </Text>
```
1. Verify that the first and third text take full width
2. Verify that the second text does not take full width
