Link auto-contribute to brave shields

As a User,
I want to allow all ads from all sites, but those who I manually added to my auto-contribute list,
so that I can support my favorite content-creators with my money, rather than cutting off their ad revenue.

Additional Information

This feature depenends on being able to manually add sites to auto-contribute, rather than the current auto-addition, with the option to manually remove individual sites, which is currently used in brave.
