Add `--option` argument to `create-window`

This patch adds a new CLI parameter to the `create-window` subcommand,
matching the existing `--option` parameter when creating a new Alacritty
instance.

This parameter allows setting up the initial window configuration from
the CLI without having to call `alacritty msg config`, making sure that
all options are set appropriately right from the start.

Closes #6238.
