This PR was squashed before being merged into the 3.x-dev branch.

Add PHP-CS-Fixer

This repo seems to be the only one that doesn't use PHP-CS-Fixer, which is a bit annoying when trying to contribute since I have to manually worry about coding standards. I'm not sure if there's a specific reason for that, so I decided to give it a try in this PR.

I took the `.php-cs-fixer.dist.php` from the framework repo and made a few adjustments. I removed `nullable_type_declaration` and `nullable_type_declaration_for_default_null_value` since those are part of the standard Symfony set. Additionally, I set `modernize_strpos` to `false` since the bundle still supports PHP >= 7.2.

I'm not sure how to run it in the CI, as some repos use fabbot while others, like the MakerBundle, use GitHub Actions.

It would be best to hide whitespace changes while reviewing.
