Add option to force local ID dictionary generation and use it

Now that we use static Identifier dictionaries by default for ITK, add an option that allows the old behaviour (on-the-fly generation of local dictionary) to be selected for e.g. debugging purposes. Should help with e.g. !40387 (merged)
