Allow conditional setting of required flag of a field

[codeflorist]

The condition property can be used to show/hide a field based on the value of a sibling field.

It would be very handy, if it were also possible to make a field required based on the value of a sibling field.

Example:

required: (siblingData) => siblingData?.whatever === true

This should influence validation as well as the * suffix of the label.

This is possible now by writing a custom validation function as well as a custom label component, but it would be very handy, if this would be working out-of-the-box.
