Bug Description

class_delegate_protocol doesn't recognize the Actor protocol as suitable for being weakly referenced.

protocol FooDelegate: Actor { }

actor Bar {
    weak var delegate: (any FooDelegate)?	// raises warning: Class Delegate Protocol Violation: Delegate protocols should be class-only so they can be weakly referenced (class_delegate_protocol)
}

Since Actor protocol already conforms to AnyObject I believe it can also be whitelisted.

Bonus idea for further consideration: how about renaming the rule into reference_type_delegate_protocol? (I don't have a strong opinion about this one.)
