bug #5464 NativeFunctionInvocationFixer - PHP 8 attributes (HypeMC, keradus)

This PR was squashed before being merged into the 2.18 branch.

----------

NativeFunctionInvocationFixer - PHP 8 attributes

The `NativeFunctionInvocationFixer` removes the leading `\` from attributes when strict is set to `true` which breaks the code.

Config:
```php
'native_function_invocation' => [
    'strict' => true,
],
```

Result:
```diff
-#[\Attribute(\Attribute::TARGET_CLASS)]
+#[Attribute(\Attribute::TARGET_CLASS)]
class Foo {}
```

This PR should fix the problem.
