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.

+/// ArgvInput represents an input coming from the CLI arguments.
+///
+/// Usage:
+///
+/// ```php
+/// $input = new ArgvInput();
+/// ```
+///
+/// By default, the `$_SERVER['argv']` array is used for the input values.
+///
+/// This can be overridden by explicitly passing the input values in the constructor:
+///
+/// ```php
+/// $input = new ArgvInput($_SERVER['argv']);
+/// ```
+///
+/// If you pass it yourself, don't forget that the first element of the array
+/// is the name of the running application.
+///
+/// When passing an argument to the constructor, be sure that it respects
+/// the same rules as the argv one. It's almost always better to use the
+/// `StringInput` when you want to provide your own input.
