Notify the main GUI thread upon receiving a close event instead of when
the windows is destroyed. Additionally there was a logic error in in
GuiReceiver::isLastWindow() that is corrected.
Fixes#6479 and #20822
displayOverlay doesn't disappear after timeout #27082Fixes#26555
### Expected Behaviour
An overlay should be displayed atop an image and then disappear after `delayms` has timed out, but it doesn't. Also, `displayStatusBar` doesn't appear to set any text on the window.
### Actual Behaviour
The overlay appears but doesn't disappear unless a mouse move event happens on the image.
### Changes
- Fixed the issue with `displayOverlay` not disappearing after the timeout.

Added argument to print notice in `roiSelector.cpp`
Related Issue : https://github.com/opencv/opencv/issues/23175
I've added a printNotice argument to `selectROI` (and it's overload) and `selectROIs` functions.
I've also updated the function declarations in `highgui.hpp`.
Tested by building locally.
