```
hpb::Arena arena;
auto foo = hpb::CreateMessage<Foo>(arena);
foo.GetInternalArena(); // this call will now be impossible
```
Before this CL, any Proxy/Ptr could get its internal arena. This
unnecessarily leaks upb internals when they should be
interacted with via hpb::interop::upb::*.

This is a very narrow edge case where touching a packed extension via generated APIs first, and then doing so reflectively will trigger a DCHECK. Otherwise, reflective APIs will work but not use packed encoding for the extension. This was likely a pre-existing bug dating back to proto3, where it would only be visible on custom options (the only extensions allowed in proto3).
To help qualify this and uncover similar issues, unittest.proto was migrated to editions. This turned up some other minor issues in DebugString and python.

This can be used by dynamic messages to validate enums instead of going through
reflection.
This removes one of the few cases where dynamic messages have to fall back to
reflection during table-driven parsing.

This CL fixes an unnecessary string copy. `Message::GetTypeName()` always
returns a copy, but we can avoid this by relying on `Descriptor::full_name()`
instead.

Everything should work without this change, because all references are done to a single definition. But the accidental duplication needs to be removed eventually.

The change is no-op for Bazel < 8, it always falls back to native providers.
When we cherry-pick --incompatible_autoload_externally to older Bazels, ProtoInfo
can be replaced with Starlark implementation, providing that users set the flag so that there is no second implementation exposed from Bazel.

This CL doesn't unbreak the bazel tests, but is yak shaving in prep for changes that will. This makes it more straightforward how the tests are broken by having bazel test rules name rust proto library targets that don't exist in bazel repo, instead of naming targets that do exist but are bogus.
Also correct unittest_edition target to match the order of words in the .proto file name (edition_unittest)

The logic to create new elements in `RepeatedPtrField` was spread across an assorted collection of specializations of `GenericTypeHandler`, individual `GenericTypeHandler` static functions, and external member and non-member functions, all living in multiple sources. Now all that logic is concentrated in three symmetric `GenericTypeHandler` specializations.

Bazel 6 falls back to native rules, because of ProtoInfo differences.
Bazel 7 is slightly degraded: Kythe flags don't work, DebugContext is left out from CcInfo and temporary files generated by the C++ compiler (but it's only useful for debugging).
Tests will be submitted in separate PRs.

I realized that as long as we implement `UpbTypeConversions` for enums, we can
easily get the blanket implementation for messages to work for enums as well.
Luckily the blanket implementation also happens to work for non-generated
types, so this gets us down to just one ProxiedInMapValue implementation for
upb.
