Re: [webrtc-pc] Use [SameObject] for the FrozenArray<T> attributes that never change

Hang on, if dictionaries are always returned "by value", meaning they are copied, and the elements of FrozenArray\<T\> are mutable (its the references that are immutable of FrozenArray), then "SameObject" would be dangerous. To ensure dictionary are copied we need to return new FrozenArrays every time.

`certificate.fingerprints[0].foo = "bar"` should be possible if I understand WebIDL correctly, but that should not mess up future `certificate.fingerprints[0]` readings.
