Write test: try all QImage formats
It is necessary to add a write test that checks all image formats supported by QImage. On several occasions the plugins failed to save one or more image formats.
The problems encountered were various:
- Writing failure (lucky case)
- Writing completed successfully but image completely wrong
- Crash
In qt_6_7_2_save.zip are contained the images saved by the plugins (heif and avif are missing) with all fixes up to MR !267 (merged).
