Have an attribute on signals to say that that signal already exists

[ahayzen-kdab]

Have an attribute on signals to say that that signal already exists, this would then allow you to declare that dataChanged already exists on the base class (eg for a listmodel).

#[cxx_qt::signals(MyObject)]
enum Signal {
    #[existing_name="dataChanged"]
    DataChanged
}

This would then generate the CXX bridge for the dataChanged method, which then means CXX does the asserts that a function exists that matches.

Do we need to check it's a Q_SIGNAL (and can we?) or is just a function enough.

Gone with #[cxx_name = "..."] and #[inherit] as attributes for now.
