8342524: Use latch in AbstractButton/bug6298940.java instead of delay

[aivanov-jdk]

Use a CountDownLatch in javax/swing/AbstractButton/bug6298940.java instead of delay.
Use Util.hitMnemonics instead of custom code to handle macOS.

I ran the updated test a few times with JTREG=REPEAT_COUNT=20, the test always passed in the CI.

I tested this as well with repeats. Looks good to me. However, I noticed that this test is newly added. Double-checking, is this intentionally open-sourced?

I intended open-sourcing the test when I submitted the bug. I see no reason why it should remain closed-source. We have been open-sourcing all the tests which can be.

LGTM, ran test on local machine (macOS sonoma 14.7) and it passses
