refactor(symfony-console): extract symfony/console into the shirabe-symfony-console crate

Move `Symfony\Component\Console` out of shirabe-external-packages and
into its own crate, so the path is
`shirabe_symfony_console::application::Application` instead of
`shirabe_external_packages::symfony::console::application::Application`.
The `delegate_to_inner!` and `delegate_command_trait_impls_to_inner!`
macros move with it.
