Sets whether the contents of the entry are visible or not.
When visibility is set to %FALSE, characters are displayed
as the invisible char, and will also appear that way when
the text in the entry widget is copied elsewhere.
By default, GTK picks the best invisible character available
in the current font, but it can be changed with
[method@Gtk.Entry.set_invisible_char].
Note that you probably want to set [property@Gtk.Entry:input-purpose]
to %GTK_INPUT_PURPOSE_PASSWORD or %GTK_INPUT_PURPOSE_PIN to
inform input methods about the purpose of this entry,
in addition to setting visibility to %FALSE.
