[swift-evolution] [Pitch] allow non-nominal type extension

[Cao Jiannan]

e.g.

extension TrackCountProvider & PublishDateProvider {
    var trackCountAndPublishDateText: String {
        var infos: [String] = []
        
        if let trackCount = trackCount  {
            infos.append("\(trackCount)")
        }
        
        if let publishDateText = publishDate?.text {
            infos.append(publishDateText)
        }
        
        return infos.joined(separator: seperator)
    }
}
