Implement new CIFilters in Xcode 26

New filters:

* [ ] CIAreaAverageMaximumRed
* [ ] CIBlurredRoundedRectangleGenerator
* [ ] CIRoundedQRCodeGenerator
* [ ] CISignedDistanceGradientFromRedMask
* [ ] CISystemToneMap

These filters have been ignored in introspection, so the ignores have to be undone as well.
