Make easier to extend SubmissionWizard with Vue.js components

[jardakotesovec]

Description:
SubmissionWizard allows to be extended with smarty templates. And smarty templates can contain Vue.js components. But since we are discouraging from Smarty use and gradually moving towards using just Vue.js components, goal of this issue is to allow to extend submission wizard without creating smarty template.

Solution:
Extend wizard.tpl to interpret if there is section.component and section.props. And for review page same thing for reviewSteps

What application are you using?

This should be easy enough to backport to 3.5 without braking changed once its tested on the main.
