PHP 8.0 introduces named function call parameters:
```php
array_fill(start_index: 0, count: 100, value: 50);

// Using reserved keywords as names is allowed.
array_foobar(array: $array, switch: $switch, class: $class);
```

Ref: https://wiki.php.net/rfc/named_params

This new sniff will detect the use of named parameters based on the support for this in PHPCSUtils as added in PHPCSStandards/PHPCSUtils 235 and PHPCSStandards/PHPCSUtils 383.

Includes unit tests.

**Open question**: should this sniff live in the `FunctionUse` category or in the `Syntax` category ?
