Issue: `Semantics.label` in iOS creates a new `Text` rather than setting Semantic container's ID
Labels: platform-ios,framework,a: accessibility,has reproducible steps,P2,found in release: 3.3,found in release: 3.7,team-ios,triaged-ios

## Steps to Reproduce
Wrap a widget in a `Semantics` widget and set a value to its `label`. Note that the child widget must internally implement a `Semantics` and has `container` set to `true`.

**Expected results:** <!-- what did you want to see? -->
1. On Android, a `View` is rendered and has `contentDescription` of `Semantics.label`.
2. On iOS, a `UIAView` is rendered and has accessibility ID and label value of `Semantics.label` .

**Actual results:** <!-- what did you see? -->
1. On Android, a `View` is rendered and has `contentDescription` of `Semantics.label`.
2.  On iOS, a `UIAView` is rendered, *but* has no accessibility label or id set. Instead, a new Text widget is created as a sibling widget of `Semantics.child`.

See screenshots attached below to visualize the issue.

Tested on Flutter 3.3.10.

```dart
Semantics(
    label: 'CheckboxID',
    child: const CheckboxListTile(
      value: true,
      onChanged: null,
      title: Text('Checkbox'),
    ),
  ),
```

Screenshots taken using Appium IDE inspector. Using Xcode's Accessibility Inspector also yields a similar result.

### Button

In these 2 images below, we can see that a `UIAView` is created but Semantics label is rendered as a new Text widget rather than setting the `UIAView`'s accessibility ID and label.

For comparison, here's how it looks like in Android.

### TextField
On a separate issue: in the case of TextField, weirdly on iOS it will properly set the `TextField`'s ID and label and not modify the value. In Android, the `TextField`'s value get merged with its Semantics label.
