Fuzzy match

As a Qt API user,

I would like to be able to match strings fuzzy,

so that I can offer fuzzy search for my application users.

—

I have been requested by my customers to add fuzzy search for a search line edit control in my applications. I can implement this in my application, but this sounds like something that ought to be offered in a common place as this tends to common across applications. Even QtCreator seems to have its own implementation.

I am suggesting to also add a Qt::MatchFuzzy flag over here: https://doc.qt.io/qt-6/qt.html#MatchFlag-enum
