RFR: 8225122: Test AncestorResized.java fails when Windows desktop is scaled. [v2]

[Sergey Bylokhov]

> This test depends on the next windows UI performance option:
> “Show window contents while dragging”, see https://answers.microsoft.com/en-us/windows/forum/all/in-windows-7-how-do-i-show-window-contents-while/18e3aee2-bcc7-4005-a45d-c5613cf6eb3c
> 
> In the default configuration, the windows may decide that the system is slow and this option should be disabled. I have found that this usually happens in the virtual environment.
> 
> When that option is disabled the resize events have come when the user completes the resize, before that the only border "rectangle" is moved.
> 
> This fix changes the test to release the mouse and complete the resize, and only after that checks the result.
> 
> Also, some old machinery is removed.
