    Introduce HasGhciState class and refactor use-sites
    
    This allows to reach the GhciState without having to keep
    track how many Monad transformer layers sit on top of the
    GHCi monad.
    
    While at it, this also refactors code to make more use of the
    existing `modifyGHCiState` operation.
    
    This is a preparatory refactoring for #10874
