Additional context

Related to SciML/SciMLBase.jl#629
I still need to add tests. I need to make a problem where the cache has jac_config and grad_config. And test that it strips the cache correctly.

This way I don't have to make dispatches for every individual cache that has jac_config or grad_config. I had to use eval(nameof(typeof(cache))) since typeof has the parametric type information, so I can't put all nothings into typeof of a concrete cache type.

Actually, I don't need to use eval. These changes should work better.

I believe this should be it for most of SciML/SciMLBase.jl#629

I think I'll need to add a test to SciMLBase making sure that strip_solution on a solution from an in place problem using an implicit method actually goes through and strips everything.
