[analyzer] Detect ObjC properties that are both (copy) and Mutable.
When an Objective-C property has a (copy) attribute, the default setter
for this property performs a -copy on the object assigned.
Calling -copy on a mutable NS object such as NSMutableString etc.
produces an immutable object, NSString in our example.
Hence the getter becomes type-incorrect.
