RFR: 4825182: DefaultBoundedRangeModel.setMinimum() changes extent unnecessarily

[Prasanta Sadhukhan]

[DefaultBoundedRangeModel spec](https://docs.oracle.com/en/java/javase/19/docs/api/java.desktop/javax/swing/DefaultBoundedRangeModel.html#%3Cinit%3E(int,int,int,int))
set maximum, minimun., extent as per the constraint "min <= value <= value+extent <= max"
Now, when DefaultBoundedRangeModel.setMinimum() is called with same "value" then because of the integer overflow in `setMinimum` method, it causes the `extent `to become 0.

Fix the integer overflow and make sure the extent is not changed unncessarily
