ZIHAN DAI 1610602884 Merge pull request #28699 from PDGGK:fix/highgui-system-exit ...

Replace System.exit(-1) with exceptions in HighGui.java (#28696) #28699

## Summary

Library code should never call System.exit() as it kills the entire JVM. Replaced all 3 instances with appropriate exceptions.

Closes #28696

## Changes

- `imshow()` with empty image: `System.exit(-1)` -> `throw new IllegalArgumentException("Image is empty")`
- `waitKey()` with no windows: `System.exit(-1)` -> `throw new IllegalStateException("No windows created. Call imshow() first")`
- `waitKey()` with null window image: `System.exit(-1)` -> `throw new IllegalStateException("No image set for window: ... Call imshow() first")`
- `InterruptedException` catch: `printStackTrace()` -> `Thread.currentThread().interrupt()`
