Function rustdoc::clean::utils::get_all_types

pub(crate) fn get_all_types(
    generics: &Generics, 
    decl: &FnDecl, 
    cx: &DocContext<'_>
) -> (Vec<(Type, TypeKind)>, Vec<(Type, TypeKind)>)

Return the full list of types when bounds have been resolved.

i.e. fn foo<A: Display, B: Option<A>>(x: u32, y: B) will return [u32, Display, Option].
