Currently the generated code contains 2 loads of ptr_ b/c it's an atomic:
one in HasSize and one in AllocateFromExisting.
Combine these to be a single load.

we can just hardcode that logic in `Message::CopyFrom`.
Also, move the implementation of `GetClassData` to the base class for zero field messages.

The edition specification in proto files will remain unchanged, but it will be immediately converted to an enum by the parser. This gives us more control over the valid set of editions and simplifies ordering (just an integer comparison now). We plan to release exactly one edition per year.

This can be used by non-C++ runtimes and generators to seed feature resolution. The output binary proto message will contain a mapping from edition to the default feature set, including whichever generator feature extensions are passed to protoc.

- Check that the maximum edition is always after the minimum
- Make sure that the minimum edition gets included in the default mapping when it's necessary

This partially fixes https://github.com/protocolbuffers/protobuf/issues/10088. The test case from that bug significantly improves with this change. However we still have a global map that does not shrink, which can still create the appearance of leaking memory, as it will not be freed until the module is unloaded.

This changes the code to use explicit constructors instead of aggregate initialization, which allows optimizations when creating and copying messages.

Create message/internal/types.h as a new leaf header
Move map_entry.h from message/internal/ to collections/internal/ where it belongs

These have preconditions around not self-swapping, so restrict is safe here.
Comparison of generated code for methods used by message_unittest,
vectorization improves.
