ErrorException from error handler static utility method

[uuf6429]

Description

• since PHP is slowly transitioning from errors to exceptions
• since it's common for devs to want to handle errors and exception in a uniform way
• (also judging by such utility code in the php documentation)

It may be beneficial to implement a ErrorException::handleError() (or similar) static method, which can be fed directly to set_error_handler().

So essentially the example here would be built into the ErrorException class.

// internal code
class ErrorException extends Exception
{
    public static function handleError(int $errno, string $errstr, string $errfile, int $errline): void
    {
        if (!(error_reporting() & $errno)) {
            return;
        }

        if ($errno === E_DEPRECATED || $errno === E_USER_DEPRECATED) {
            return;
        }

        throw new \ErrorException($errstr, 0, $errno, $errfile, $errline);
    }
}

// userland code
set_error_handler(ErrorException::handleError(...)); // or array call or whatever

Implementation-wise I don't think this would cause any BC issues, nor should it be invasive.

Looking at Symfony's error handler, there's a lot more going on in there, so this general approach probably won't cut it for Symfony.

But there are otherwise many implementations that are similar to the example or simple/poorer: https://github.com/search?q=language%3APHP+set_error_handler+errorexception&type=code (essentially this is what I'd like to tackle mainly)
