* Remove the 'set default from all bitflags items' behavior of `RNA_def_property_enum_bitflag_sdna`. * Add some minimal sanity check regarding bitflag enums that also define an `items` runtime callback. It currently assumes that if a valid set of items is also statically defined, the items callback will return a subset of these. Implements #143538.
