[php-src] Issue #20974: Request to add support for `Trait` in the extension layer

Issue: https://github.com/php/php-src/issues/20974
Author: matyhtf

### Description

Request to add a new ZendAPI: `zend_class_use_traits` that will allow internals classes in the extension to use Traits.

```c
static zend_class_entry *register_class_TestClass(zend_class_entry *class_entry_TestClassInterface) {
	zend_class_entry ce, *class_entry;

	INIT_CLASS_ENTRY(ce, "TestClass", class_TestClass_methods);
	class_entry = zend_register_internal_class_ex(&ce, NULL);

	zend_class_use_traits(class_entry, 2, class_entry_TraitA, class_entry_TraitB);
}
```
