These will become meaningless once we migrate to editions. In the meantime, we've implemented APIs to expose the differences between proto2 and proto3 in terms of the features we plan to release in edition 2023.

For legal reasons we unfortunately cannot accept any external contributions to
the well-known type protos, so this change reverts the small number of changes
we have received so far.

No need for a loop that that calls tryConsumeString or tryConsumeByteString repeatedly, since ConsumeByteString already loops itself.

In this CL we're adding the barebones infrastructure to generate Rust proto messages using UPB as a backend. The API is what we call a V0, not yet production-quality, not yet rigorously designed, just something to enable parallel work.
The interesting part of switching backend between UPB and C++ will come in a followup.

This fixes the following issue:
- In `FieldSet#getMessageSetSerializedSize` we delegate to `LazyField` for getting its size.
- Before this change, in `FieldSet#writeMessageTo` we do not delegate to LazyField's `byteString` method. Instead, we call `getValue` on the `FieldSet`.
- It's not guaranteed that `fieldSet.getSerializedSize() == fieldSet.getValue().getSerializedSize()`.
In particular, this can lead us to run into the message "Serializing com.google.protobuf.DynamicMessage to a byte array threw an IOException (should never happen)" because of mispredicted output size.
We fix the issue by following similar logic to `MessageSetSchema`- if "getSerializedSize" delegates to the LazyField, then the serializer should as well.

For now, we'll just be hiding syntax getters on FileDescriptor. Later on this will likely grow to include other APIs that distinguish between proto2/proto3.

As part of go/protobuf-editions, we will be abandoning `syntax` in place of the new editions framework. The first edition will turn each difference between proto2 and proto3 into a more targeted *feature* placed on proto descriptors. In preparation for this, we want to migrate everyone off direct inspection of `syntax`.
