Revert get_class() simplification in ObjectType::equals() to fix TemplateObjectType regression

The `get_class($type) !== static::class` check was too strict - it rejected
TemplateObjectType instances that should be comparable by class name, since
TemplateObjectType extends ObjectType but has no equals() override. This caused
false `varTag.type` errors when using @var with generic template types.

Reverts to explicit instanceof checks: reject EnumCaseObjectType and
GenericObjectType (when $this is plain ObjectType), but allow other ObjectType
subclasses like TemplateObjectType.
