macos: allow association with .command file type

Browse Source 
Implement an app delegate to receive a callback when the system
requests that we open `.command` files, and then ask the mux
layer to spawn a window for it and execute it via the shell.

Also allow handling `.sh`, `.zsh`, `.bash`, `.fish` and `.tool`,
per kitty.

* macOS: allow association with `.command`, `.sh`, `.zsh`, `.bash`, `.fish` and
`.tool` scripts, so that those can open and show their output in the
terminal. [#2871](https://github.com/wez/wezterm/issues/2871)
