Previously, some but not all of these classes stored `Context* context_`.
These will be used in a followup change to consider strip_nonfunctional_codegen in field comments.

Also, add reference overloads of DynamicCastToGenerated which terminate on failure like dynamic_cast would do on an environment without exceptions.

This removes a large chunk of the reflection we need to do during descriptor builds, and will make it possible to migrate descriptor.proto to editions. It also removes some special treatment of the C++ runtime, which happens to have easy access to protoc internals today.

This is meant to optimize our editions handling before rolling it out more widely to proto2 and proto3 under the hood. As it's implemented today, every file descriptor would need to allocate its own duplicate FeatureSet for either proto2 or proto3 (plus additional ones per proto2 group).

Python 3.12 has removed the `distutils` module, so we need to stop relying on
it. Most of the parts we were using had a straightforward replacement in
`setuptools` or elsewhere in the Python standard library. I couldn't find a
good replacement for `distutils.command.clean`, though. We were only using it
to enable `python setup.py clean`, so I just removed that functionality since
directly invoking setup.py is deprecated anyway.
While I was looking at this I realized that our python/release.sh script is
unused, so I also removed that.

This hooks up legacy proto2/proto3 editions, but prohibits them from being used in proto files. These will be hooked up directly to `syntax` declarations in a later change.

These exist so that new features can specify their proto2/proto3 defaults. This will allow for easier migration to editions, and also allow us to migrate more proto2/proto3 code paths to common editions code. The latter will provide give us early coverage over a lot more of editions.

This is preparation work to merge the vtable with the `ReflectionPayload`
object to reduce the size of MapField by 8 bytes.
