Fix texture-based native child widget stretching
The new rhi-based approach to compositing has a difference in transform
calculation which becomes relevant with native child widgets (so when
the flush offset is > 0). This is incorrect, so restore how 6.3 and
earlier did this calculation.
Pick-to: 6.4
Fixes: QTBUG-107814
