This should be moved into the .cc file in an anonymous namespace.

If we had Clone() calls for these contents, you wouldn't have to duplicate the data they need in structs. So the variant would just be std::variant<LinearGradientContents, RadialGradientContents, ...>.
GetContents would then just call Clone(), but storing it in a variant would allow you to visit the actual type.
Just a suggestion, feel free to punt since this is good.

Oh, so rather than have the data at all, just make color source contents cloneable. That makes sense but would also require more refactors, since we store this on paint and do a lot of type based dispatching.

Though we could also change ColorSourceContents to remove the inheritance and change its behavior based on the variant its given.

Since that's what it does.

This would also me to create a type safe visitor to pull out the data required for #51778
