Improve GraphQL Authorization DSL

What does this MR do?

Currently GraphQL field authorization happens like this:

class ProjectType
  field :my_field, MyFieldType do
    authorize :permission
  end
end

This MR allows us to authorize like this:

class ProjectType
  field :my_field, MyFieldType, authorize: :permission
end
