feat(Wizard - next): Additional features/enhancements

[jpuzz0]

Depends on: #7731

• Ability to hide steps using hook called useToggleWizardStep (or something similar to this) or by passing a isHidden flag to WizardStep usages directly.
• Inclusion of index for onNext, onBack, and onNavByIndex callbacks.
• status or hasError prop can be added to control whether a step's nav label displays an ExclamationCircleIcon
• Getter and setter for WizardControlSteps can be added to make it easier to update any aspect of the list of steps maintained by Wizard's context.
• Give WizardStep the ability to control any single prop passed to the footer of the parent by providing a footer prop for WizardStep directly.

Should also update examples to include these enhancements.
