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

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