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

Move `Symfony\Component\Process` out of shirabe-external-packages and
into its own crate, so the path is `shirabe_symfony_process::Process`
instead of `shirabe_external_packages::symfony::process::Process`.
