Skip "StatusIndicator" window in Auto-Type window list (#7526)

Starting with macOS 12.2, when the audio recording indicator is shown, the
"Window Server" process injects a "StatusIndicator" window into the list of
active windows, which messes with Auto-Type's window title matching. This
window has an Alpha value of 1 (so technically, it is not invisible), and it
is always in front of all other windows. Hence, the only way to skip it is by
title and owner name.

Fixes #7418
