function datetime_range_view_presave

Implements hook_ENTITY_TYPE_presave().

When a view is saved using the old string or standard plugin format for Datetime Range filters or sorts, they will automatically be updated to Datetime filters or sorts. Old plugins usage must to be considered deprecated and must be converted before 9.0.0, when this updating layer will be removed.
