Add extension to has image property components

[Mx-Iris]

I found that there are a lot of objects with image property, if I add setImage method for them one by one will lead to a lot of repetitive code, so I abstracted a protocol, in the future as long as the object with the image property to conform with this protocol can get setImage method.

Thank you for your patience and for submitting your pull request to the Kingfisher library. I apologize for the delayed response, as I only had the opportunity to review it thoroughly today.

I am impressed with the functionality introduced in your PR, and I see great value in integrating it into the Kingfisher library. However, we have recently made several updates to improve strict concurrency, including adding @MainActor annotations to image setting methods. Given these changes, I believe your contribution would fit perfectly in the upcoming major release.

Could you please rebase your changes onto the latest v8 branch and submit a new PR? I am eager to review it and include it as a stable feature in our next release.

Thank you once again for your valuable contribution and effort.

I have merged the latest code and added some UIKit components, I found that there are a lot of UIConfigurations that have the image property, but this implementation of mine only takes into account AnyObject, and if I need to be compatible with the value type, I need to change the base property of KingfisherWrapper from let to var, do you have a Do you have a better way to implement this feature?

Don't worry! Let me try to handle it.

Ok, thanks for submitting a new PR for me and adding concurrency, I'm not familiar with swift concurrency so I didn't understand what you said above, I'll close this PR then, feel free to @ me if you have any questions!
