Centralize copying of tables functionality

[jluethi]

We currently do different table copying in:

• the tasks._zarr_utils => _copy_tables_from_zarr_url used in illumination_correction (will be added by 723 Fix illumination correction task not copying tables #724)
• the tasks.apply_registration_to_image task itself

Maybe other places?

Let's centralize this functionality. Should this be functionality of a future Fractal OMEZarrImage class? (see #678)

We can handle potential timeouts & file locking in that area to avoid any race conditions. And have a more general, public table copying functionality available in the API after that.
