RFR: 8341984: Use PassFailJFrame for TimeChangeButtonClickTest.java

[Alexey Ivanov]

Refactor the test `javax/swing/JButton/TimeChangeButtonClickTest.java` to use the `PassFailJFrame` framework to handle the tester's decision on whether the test passes or fails.

I reformatted the instructions for performing the test into HTML.

I preserved the test UI panel which contains the button to press and the label with button press counter.

The updated test is shorter by nearly 100 lines.
