We use CVDisplayLink in MTLLayer to blit content to the screen.
While working onJDK-8312198 noticed that from macOS 14 many functions under CVDisplayLink are deprecated : https://developer.apple.com/documentation/corevideo/cvdisplaylinkcreatewithactivecgdisplays(_:)?language=objc
We have Metal specific CAMetalDisplayLink which can be used to blit the MTLLayer : https://developer.apple.com/documentation/quartzcore/cametaldisplaylink?language=objc
Also looks like using CADisplayLink/CAMetalDisplyaLink takes care of display sleep and wakeup scenarios : https://developer.apple.com/documentation/macos-release-notes/appkit-release-notes-for-macos-14#Display-Link. So we can remove additional code that we have now to handle such scenarios :JDK-8304825, JDK-8312198.
We need to replace deprecated CVDisplayLink with CAMetalDisplayLink.
This also needs good amount of testing to make sure everything works fine.
