preconditioner Ic without the solver type

[yhmtsai]

This PR makes the preconditioner IC wrapper without SolverType. It moves the solver type into the factory operator. When we provide the solver, the SolverType is useless but we still need to put it into template. the type requirement is the same as original. Ic<SolverType>::build().on(exec); -> IcWrapper::build().with_l_solver_factory(IcWrapper<SolverType>(exec)).on(exec) or any IcWrapper::build().with_l_solver_factory(linop_factory).on(exec); It's also good for ResourceManager.

TODO:

• [ ] change the explicit type as when merging SolverBase
• [ ] add IluWrapper

The whole factorization preconditioner setup needs to be reworked (https://github.com/ginkgo-project/ginkgo/issues/472), do you need this urgently? I am not really happy with adding a second *Wrapper type that does the same thing and likely removing it with 2.0 again.
