Refs #35381 -- Delegated ArrayField element prepping to base_field.get_db_prep_save.

Browse Source 
Previously, ArrayField always used base_field.get_db_prep_value when saving,
which could differ from how base_field prepares data for save. This change
overrides ArrayField.get_db_prep_save to delegate to the base_field's
get_db_prep_save, ensuring elements like None in JSONField arrays are saved
correctly as SQL NULL instead of JSON null.
