The goal of this PR is that `ErrorHandler::handleException()` handles `\Throwable` directly and forwards it without altering it.

This would avoid a blank page on errors when we've disabled the default error controller. e.g:
```yaml
framework:
error_controller: null
```
So, we will show you the default HTML error page.

**Issue**
There is no easy way to catch PHP warnings, though some progress has been made in this area for PHP 8.0 (https://wiki.php.net/rfc/consistent_type_errors).
**Before**
```php
$file = file_get_contents('unknown.txt');
// PHP Warning: file_get_contents(unknown.txt): failed to open stream: No such file or directory
// workaround:
$file = @file_get_contents('unknown.txt');
if (false === $file) {
$e = error_get_last();
throw new \ErrorException($e['message'], 0, $e['type'], $e['file'], $e['line']);
}
```
**After**
```php
$file = ErrorHandler::call('file_get_contents', 'unknown.txt');
// or
$file = ErrorHandler::call(static function () {
return file_get_contents('unknown.txt');
});
// or (PHP 7.4)
$file = ErrorHandler::call(fn () => file_get_contents('unknown.txt'));
```

Alternative of https://github.com/symfony/recipes/pull/630
This would solve the bug in `bin/console.php` and `public/index.php` for existing projects migrating to 4.4 without requiring symfony/debug.

Mainly for API-based apps that don't require TwigBundle to get the correct exception response according to the request format (aka `_format` attribute).
✔️ [RFC7807](https://tools.ietf.org/html/rfc7807) compliant for JSON and XML formats.
---
This introduce a new `ErrorRenderer` service that render a `FlattenException` into a given format:
```php
use Symfony\Component\ErrorHandler\ErrorRenderer\ErrorRenderer;
use Symfony\Component\ErrorHandler\ErrorRenderer\HtmlErrorRenderer;
use Symfony\Component\ErrorHandler\ErrorRenderer\JsonErrorRenderer;
$renderers = [
new HtmlErrorRenderer(),
new JsonErrorRenderer(),
// ...
];
$errorRenderer = new ErrorRenderer($renderers);
return new Response(
$errorRenderer->render($exception, $request->getRequestFormat()),
$exception->getStatusCode(),
$exception->getHeaders()
);
```
The built-in error renderers are:
| Format | Class |
| --- | --- |
| html | HtmlErrorRenderer |
| json | JsonErrorRenderer |
| xml, atom | XmlErrorRenderer |
| txt | TxtErrorRenderer |
And you can add your own error renderer by implementing the `ErrorRendererInterface` and tagging it with `error_handler.renderer` in your service definition.
Creating your own error renderer for a built-in format will end up replacing the related built-in error renderer.
