Suport label for multi select field

### Is your feature request related to a problem? Please describe.

The multi select fields does not display the title of the field as label.

```js
oneOfMultiEnum: {
type: 'array',
uniqueItems: true,
title: 'select all that apply'
items: {
oneOf: [
{ const: 'foo', title: 'My Foo' },
{ const: 'bar', title: 'My Bar' },
{ const: 'foobar', title: 'My FooBar' }
]
}
}
```

The label "select all that apply" is not displayed in the form. Even if I enforce the label in the ui schema it does not work.

I was able to achieve that if I wrap my control in a group, but that gives more emphasis in the group title than I wish it would. I want the label to be in the same format as the other labels are.

### Describe the solution you'd like

Display the title as label as it would for the other fields automatically without any extra configuration.

### Describe alternatives you've considered

I'm fine with it being a opt-in feature.
