 Remove `RandomizedParams` from `AppModuleSimulation` interface. Previously, it used to generate random parameter changes during simulations, however, it does so through ParamChangeProposal which is now legacy. Since all modules were migrated, we can now safely remove this from `AppModuleSimulation` interface.
