Add prop attributes when needed

Problem/Motivation

As with components with loops on slots, it is no more possible to inject a div like in #3486050: [2.0.0-beta5] Layout Builder: fix d&d remove temporarily UI Styles support with the UI Styles classes, check components if proper prop attributes should not be created instead.

Then decide if we will go on a manual prop attributes declared or introducing a mechanism.
