Fix Darwin availability bits for command payloads: (#29468)

1) Add missing isForCommandPayload=true to declarations of the old command payload names. Otherwise we were ending up with SetUtcTime being marked provisional, which is not backwards-compatible. 2) We need to declare fields in the old-name command payloads with the right availability, since the availability in the super-class is "too new". The implementation then needs to use @dynamic. This is similar to how structs work. 3) SetUTCTime cannot be provisional (and hence unavailable) if SetUtcTime is supposed to be available and inherits from it. This requires exposing SetUTCTime and its fields in the first release where we will update Matter.framework in the Xcode SDK to the setup where we started doing "provisionally available". Items 1 and 2 are handled by using "completeDecl" for both the old and new name.
