This is a step towards separating the mutable state on principals from const state which can be made threadsafe. The remaining mutable fields will either need to be moved off of nsIPrincipal or made threadsafe to destroy (e.g. using nsMainThreadPtrHandle) and stored behind a mutex. Serialization is handled for most types using a separate Deserializer class, like how it was handled with `nsIURI` mutators. SystemPrincipal wasn't changed as the `Read` method is a no-op for that class. Differential Revision: https://phabricator.services.mozilla.com/D115092
