Window decorations: added events to move or resize window

[java-pik]

Hi,

As mentioned in my previous issues #960 , I'd like to add an event that lets you know when a Windows user starts and finishes moving or resizing a window.

I've made the necessary changes to make this feature as lightweight as possible, while remaining consistent with the other existing features.

In the pull request, I did not include the new dll files.

Best regards
