Many times, I had to access raw tokens, and each time I used reflection or other hacks
to get theses values. So I think it's time to expose this property properly.

For example, if you want to create a command that wrap a proces, with "pass thru" arguments,
you need that.

Examples:

#!/usr/bin/env php
<?php

use Symfony\Component\Console\SingleCommandApplication;
use Symfony\Component\Process\Process;

require __DIR__ . '/vendor/autoload.php';

$command = new SingleCommandApplication('ls');
$command->ignoreValidationErrors();
$command->setCode(function ($input) {
    $p = new Process(['ls', ...$input->getRawTokens()]);
    $p->setTty(true);
    $p->mustRun();
});
$command->run();

---

Note

In castor, we also strip all options until the command name

$parameters = [];
$keep = false;
foreach ($input->getRawTokens() as $value) {
    if ($value === $input->getFirstArgument()) {
        $keep = true;

        continue;
    }
    if ($keep) {
        $parameters[] = $value;
    }
}

It could be nice to add support for this too?
