Do not use the product name "Qt Quick Designer" as UI text

Using the product name "Qt Quick Designer" in Qt Design Studio context is confusing to users.

Let's replace it in Tools > Options > Qt Quick (and anywhere else it might appear in the UI) with something more generic or descriptive, such as "Form Editor".

soili_vainamo, brook_cronin_qt: Would you have a suggestion for a better term based on user feedback?

I also never found "Form Editor" a descriptive term, because we don't have "forms" in Qt Quick (like we do in widgets). Do you have an opinion on whether we should also try to find a more descriptive name for it and what could it be?
