Use 128-bit hexadecimal string tokens generated with /dev/urandom instead of UUIDs for xdg-foreign handles, removing the libuuid dependency. Update readme and CI. Closes #2830. build: remove xdg-foreign feature With no external dependencies required, there's no reason not to always build it. Remove WLR_HAS_XDG_FOREIGN as well.
