Symfony version(s) affected: 5.2.x

I broke symfony, sorry !

Description

Signal handling does not work well with question!

How to reproduce

Use bin/console make:controller and then press CTRL+C
=> it does not work anymore until you press enter

Possible Solution

Empty this list https://github.com/symfony/symfony/blob/5.x/src/Symfony/Component/Console/Application.php#L94
Most of the time, we don't care about signal. It's only useful for long running process. But since we use this list before running the command, the "Signal To Symfony Event" feature will become hard to implement. We may register signal listener if the command implement a certain insterface.

The other solution would be to not use fgets but stream_select()

Additional context

I created a simple reproducer:

<?php

pcntl_signal(SIGINT, function () {
    dump('CAUGHT');
});
pcntl_async_signals(true);


$stream = \STDIN;
$what = fgets($stream, 4096);

dump('AFTER');

=>

php test.php 
^C^C^C^C
^ "CAUGHT"
^ "CAUGHT"
^ "CAUGHT"
^ "CAUGHT"
^ "AFTER"

As you can see, I pressed 4 times CTRL+C and it did not worked until I pressed enter
