Mitchell Hashimoto cc690eddb5 macOS: Implement basic bell features (no sound)
Fixes #7099

This adds basic bell features to macOS to conceptually match the GTK
implementation. When a bell is triggered, macOS will do the following:

  1. Bounce the dock icon once, if the app isn't already in focus.
  2. Add a bell emoji (🔔) to the title of the surface that triggered
     the bell. This emoji will be removed after the surface is focused
     or a keyboard event if the surface is already focused. This
     behavior matches iTerm2.

This doesn't add an icon badge because macOS's dockTitle.badgeLabel API
wasn't doing anything for me and I wasn't able to fully figure out
why...
