This fix corrects a behavior of `var_export()` that was mostly "hidden" until PHP 8.1 introduced:
* properties with object initializers
* constants containing object references
* default values of class properties containing `enum`s
Since `var_export(..., true)` is mostly used in conjunction with code generation,
and we cannot make assumptions about the generated code being placed in the root
namespace, we must always provide the FQCN of a class in exported code.
For example:
```php
<?php
namespace MyNamespace { class Foo {} }
namespace { echo "<?php\n\nnamespace Example;\n\n" . var_export(new \MyNamespace\Foo(), true) . ';'; }
```
produces:
```php
<?php
namespace Example;
MyNamespace\Foo::__set_state(array(
));
```
This code snippet is invalid, because `Example\MyNamespace\Foo::__set_state()` (which
does not exist) is called.
With this patch applied, the code looks like following (valid):
```php
<?php
namespace Example;
\MyNamespace\Foo::__set_state(array(
));
```
