IWizardFactory: Create wizards with factoryCreators

Do not use the object pool to hold potential wizards. Register
FactoryCreator functions with IWizardFactory instead and use
those to create the wizards when necessary.

This saves us a couple of cycles during startup since we can now
delay construction of all wizards and it makes us more flexible
wrt. managing the lifecycle of the wizard factories.
