The value stored in `_has_inlined_fields` is derived directly from `FieldLayoutInfo` and is only used for a getter. Since `ClassFileParser` already retains this in `_layout_info`, a separate duplicate member is unnecessary. With this change, the getter returns the value directly from the stored `FieldLayoutInfo`, removing the extra member while preserving existing behavior.
