Suggest remove QtDesignStudioComponents

Why

• Don't support QtForMCUs
• (important) Performance and footprint concerns, most of them are created by Shape item, it shall be QtQuickItem base like other default QML types.
  • the created QML cannot be used further in production.
• Lacking API and use case (code snippet) documentation, engineers & designers don't know how to use it.
• maintenance doesn't bind with Qt or QtForMCUs
• (important) the designer (QDS user) has to remove/fix the invalid code manually, fixing it requires coding and QML skills, it is very difficult for designers, a huge bad impression on all Qt products.

Actions
