config: add toplevel-tag=TAG

Browse source 
Add support for the new xdg-toplevel-tag-v1 Wayland protocol, by
exposing a new config option, `toplevel-tag`, and a corresponding
command option, `--toplevel-tag` (in both `foot` and `footclient`).

This can help the compositor with session management, or custom window
rules.

Closes #2212
