Follow up to #197311 and based on the feedback on that PR. One way a Python synthetic formatter can construct a child is with `SBValue::GetSyntheticChildAtOffset`. However those values were are not marked as having been generated by `SyntheticChildren`. This means the previous PR (#197311) did not apply to them as would be expected. The fix is to call `SetSyntheticChildrenGenerated(true)` on the child values created in `GetSyntheticChildAtOffset`. Assisted-by: claude (tests and review)
