Pass common keyword arguments to local updaters in a NamedTuple `internal_kwargs`

Pass common keyword arguments to local updaters in a keyword argument internal_kwargs that stores them in a NamedTuple instead of individually/splatted into the updater. Many updaters don't use most of the keyword arguments being passed to them from alternating_update: https://github.com/ITensor/ITensorNetworks.jl/tree/v0.11.6/src/solvers/local_solvers so that would simplify the code a lot.

I plan to use that design in ITensorTDVP.jl v0.4: https://github.com/ITensor/ITensorTDVP.jl/pull/74 and I think it is quite nice, since then updaters only need to do a bit of extra work to extract the keyword arguments they are actually using. updater_kwargs will still be splatted into the updaters.

@b-kloss I think we discussed this design and decided against it but now I'm convinced it is the way to go since it makes most updater definitions a lot simpler.

Start in src/solvers/local_solvers and trace alternating_update to see how common keyword arguments reach each local updater. Compare the proposed internal_kwargs NamedTuple design with the referenced ITensorTDVP.jl pull request 74. Done means the local updater interfaces consistently use internal_kwargs while updater_kwargs remains splatted separately.
