The target validity check used window_pane_visible but that may be false

if the pane is zoomed, so instead add a new function to just check if
the pane is actually on screen (most commands still want to accept panes
invisible by zoom). Also reject panes outside the window for various
special targets. Problem reported by Sean Haugh.
