BUGFIX: Respect type declaration when building class-schema

Without this change, any class property is ignored, if it has no `@var`
tag. As soon as a property lacks that tag, the early return in method
`evaluateClassPropertyAnnotationsForSchema` kicks in.

When using type declarations, this is nonsense, though. This change
thus makes sure the type is fetched from the native type declaration
if no `@var` tag is found. If a `@var` tag exists, it takes precedence.
This allows to do things like this to declare typed collections:

```php
/**
 * @var Collection<AnnotatedIdentitiesEntity>
 */
#[ORM\ManyToMany(indexBy: 'author')]
protected Collection $annotatedIdentitiesEntities;
```
