Harmonize project/file creation operations between IDEs

What

• Validate that creation wizards (project & file) contain sensible steps, are informative, and behave symmetrically in Qt Creator, Visual Studio and Visual Studio Code
• Validate that the projects created in Qt Creator and Design Studio are mutally useful in the other tool.

Why

• Any friction and non-intuitiveness will be experienced by the majority of users as this is commonly used functionality. 

Dependencies

• Visual Studio Code integration
• Visual Studio integration 
• Qt Design Studio

User stories / Acceptance criteria

• As a user I want to create projects in one tool and continue using the created project in another tool. 
• As a user I want to create the project using the templates and the same attributes, irrespective of the tool in which I create it (this likely does not concern Qt Design Studio).
• As a user I want to create files using the templates and the same attributes, irrespective of the tool in which I create it. 

Tasks

• Validate the iconography of the project templates.
• Validate the iconography of the file templates. 
• Remove compat-instances of the templates (since Qt 5 is deprecated by the time Qt Creator 17 is released). 
• Ensure that user-displayed content is in synchrnoy with equivalent Visual Studio / Visual Studio Code wizards (number and names of the templates, descriptive text)
• (Continuity beyond the original definition) Create the collaboration-related user stories for the Qt tools portfolio - essentially: a project begun in tool X can be continued in tool Y without need of manual editing of project files
