Current behavior 😯

Since the active focused element is button and we are missing required attribute on it screen readers (mac voiceover) is not recognizing that the "select" field is required.

Notice that we are missing "required" state on MuiSelect-select button.

To fix this we need to add the following

 SelectDisplayProps: {
     'aria-required': props?.required
}

Expected behavior 🤔

"required" or "aria-required" to be set appropriately when we set required prop on "Select"

<TextField select required />

or 

<Select required />
