Add an protobuf::__internal::SealedInternal trait

The purpose of this trait is that it is declared as a supertrait of the traits that we don't want application code to implement (like "Proxied" and "MessageView"); application code can see those traits but not the supertrait, which enables them to use them but not implement them.

Implement ctype=CORD for singular string & byte fields

- We introduce two new view types ProtoStringCow and ProtoBytesCow.
 - In UPB, for cord field accessors we always return a Cow::Borrowed.
 - In C++, for coed field accessors we check if the underlying absl::Cord is flat (contigous) and if so return a Cow::Borrowed. If it's not flat we copy the data to a ProtoString and return a Cow::Owned.
   - We expect the absl::Cord to be flat almost all the time. We have experimentally verified that for small strings (<4 KiB) and less than 6 appends the cord is in fact flat [1].
 - This change lifts the requirement of all ViewProxy types to be Copy. Our Cow types cannot be Copy because the owned types aren't copy.
