bug#56198: Request to delete window with mouse event

[carlmarcos]

I frequently split my windows,  I usually kill the buffer using the menu bar.  But this leaves me with the window open with some other buffer.  Would like to request some facility to delete a window (delete-window) using the mouse, as I frequently do for `kill-buffer'.  Perhaps the capability could be inserted in the window mode-line.  Where  one can usually turn off a minor-mode with the mouse.
