feat(toggle): display as block when justify or alignment properties are defined (#29802)

- Change the toggle's `display` property to `block` when the `justify` or `alignment` property is set. 
- Set the default `justify-content` style to `space-between` so that a toggle with `width: 100%` set without `justify` or `alignment` set will still have the same default 
- Set the default `align-items` style to `center` so that a toggle with `width: 100%` and `label-placement="stacked"` set without `justify` or `alignment` set will still have the same default 
- Modifies the `label` e2e test to remove the explicit width as setting the property will make them full-width 
- Adds two examples to the `label` e2e test of labels that do not have `justify` set but use `width: 100%` to ensure they are working as expected without it 
- Adds one example to the `label` e2e test of a long label that uses `justify` to ensure it still wraps properly
