1d6e68e6 - [analyzer] Conversion to CheckerFamily: NSOrCFErrorDerefChecker (#151171)

[analyzer] Conversion to CheckerFamily: NSOrCFErrorDerefChecker (#151171) This commit converts the class `NSOrCFErrorDerefChecker` to the checker family framework and simplifies some parts of the implementation (e.g. removes two very trivial subclasses of `BugType`). This commit is almost NFC, the only technically "functional" change is that it removes the hidden modeling checker `NSOrCFErrorDerefChecker` which was only relevant as an implementation detail of the old checker registration procedure.
