[Win] Ensure the file picker gets closed when its owner window is closed

This change is a fix to a UX issue that can happen in rare
circumstances where the owner of the file picker dialog can be
closed while the dialog itself stays open.

In normal operation, this doesn't happen because the owner window
is disabled. While disabled, the user can't click anything on the
window, including the X button on the top right.

But programmatically, it is possible. For example, another program
can send WM_CLOSE to the owner window, leaving the dialog open.

With this change, we detect such situations and close the dialog.
