codgen: generate doc_alias for static_type

[bilelmoussaoui]

this allows finding *_type() functions using their c names

See gtk-rs/gtk4-rs#383 for the end result

That of course only helps for enums/flags and not for boxed/shared/object types :) Not sure how useful that is overall.

For boxed/shared/object types, we need a way for glib::wrapper! to add the doc aliases which is not possible as far as I can tell, you can't stringify something and pass it to #[doc(alias = "x")] if type_ is passed

I don't think it's super useful, but it would reduce the questions of how can I get get_type() for this type. Especially if people are copying a C example/looking at the C docs

So I suppose this is something we should just close?

Do doc aliases on trait impls actually work? I thought they only work on trait definitions

They do, see https://gtk-rs.org/gtk4-rs/stable/latest/docs/?search=gtk_widget_get_css_name and I still think we should land this one btw. The fact we can't get a doc alias for types using glib::wrapper! is something that might get fixed in the future but shouldn't block what we can improve already.

Sure, why not. Doesn't seem too useful for only enums/flags but it's something :)
