RFR: 8339233: Test javax/swing/JButton/SwingButtonResizeTestWithOpenGL.java#id failed: Button renderings are different after window resize [v3]

[Manukumar V S]

> This is a highly intermittent failure, and it failed only once in CI on a particular windows machine and passed on all other runs. 
> 
> Failure reason:
> When the button was displayed for the first time, the focus rectangle drawn on the button text(Button A) was not seen(failure images attached in the bug).
> 
> Fix:
> To stabilize the test, I have added a line -> button.setFocusPainted(false), so that the focus rectangle will not be painted
