8264786: [macos] All Swing/AWT apps cause Allow Notifications prompt to appear when app is launched

[mrserb]

The fix for the JDK-8187639 reimplemented the tray icon messages using the standard notification center, it worked fine on macOS 10.9. But on the new macOS, the usage of that API requests permission from the user. Since the code was added to the NSApplicationAWT this request is always shown even if the app does not use tray icons. This fix moves the code to the tray icon itself. I have tested this on macOS 11.2. It will be good if someone can check macOS 10.14 or macOS 10.15.

Please confirm if it is working in 10.14 and in multiscreen environment. Also, I guess a testcase can be written to see if notification center is coming up for normal awt non-trayicon app(obscuring normal awt window or not)

BTW, I see from https://developer.apple.com/documentation/foundation/nsusernotificationcenter?language=objc
that this class is deprecated, so I think we should not use this way of notifying user and find some other alternative or do away with this or else we will get new problems like this in newer releases.

I think we should use https://developer.apple.com/documentation/usernotifications?language=objc "UNUserNotificationCenter" instead which is the favoured way since Mohave, it seems.

I cannot confirm that it works on 10.14 since I do not have such a system, this is why in the description of this PR I requested to check the fix by someone on 10.14/10.15. Thanks to Alexander who confirm it on 10.15.

To test this functionality the user will need to enable the notification center, which should be disabled by default for the execution of our tests, then checks that the "Do not disturb" is not set for the current time, remove the java from the allow/disallow list. And then the user should return all that back. If some step will be skipped it will affect the tests executed after. I prefer do not to request that.

I know, this information is already in the jbs. When we will move further from the macOS10.14 in our JDK trains we probably should migrate to the new API.
