The toolchain type is consumed by proto_library and produced by proto_toolchain rule. As such it's a private dependency, because both rules are now part of protobuf repo.
There are some early adopters of --incompatible_enable_proto_toolchain_resolution that might be broken from this: grpc, rules_go, rules_ts, rules_rust, rules_lint, because they have implementation that is not using proto_common. Those repositories need to define their own proto_lang_toolchain and consume it with proto_common.compile.

Use paths.is_normalized and paths.is_absolute from bazel skylib. Upgrade skylib to latest version that has the implementation.
Use copybara for the differences in STRIC_DEPS_FLAG_TEMPLATE.
Implement native_bool_flag to read native flags and use them in proto_library. Those are implemented in such a way, that they can be replaced in place with starlark bool_flag targets.
Implement version check for PackageSpecificationInfo. It's only available after Bazel 6.4.0.
Tests will be submitted in separate PRs.

Enable the Starlark rule only on Bazel versions, that have the Starlark version of ProtoInfo provider. That's needed, because only that exposed _transitive_proto_info field that's used in the rule.

Move toolchain helpers into a separate private file. After the migration those should be removed, so let's not make it a new public APIs. Copybara also handles differences in toolchain type labels.
Remove ProtoLangToolchainInfo from proto_common. Providers need special care when moving and will be moved last.
Read INCOMPATIBLE_ENABLE_PROTO_TOOLCHAIN_RESOLUTION from native proto_common. This is a BuildLanguageConfiguration flag (load time flag) and may only be read through native support. Add a dependency to the latest bazel_features that supports this check. On older Bazel versions fail if ALLOWLIST is configured.
Implement version check for PackageSpecificationInfo. It's only available after Bazel 6.4.0.
The rest of the implementation matches Bazel version. Tests are quite extensive and will be submitted in separate PRs.

The functionality is enabled when the proto_one_output_per_message option used by C++ Lite is enabled.
This mirrors the behavior of C++ lite protos.

They are not needed after the rules are move into protobuf repo.
Except for the reference to toolchain type, which is currently in rules_proto and can be moved after the implementation is moved into protobuf repo.

This is needed to make protobuf/bazel package minimal for other proto rules.
Keep 4 public bzl files in upb/bazel. They end up under protobuf/bazel, and they are legitimately used by other repositories.
Move upb_proto_library_internal/* under bazel/private. Those are utilities used in the rules. Moving them one level deeper makes protobuf/bazel package clean for other rules.
Move build_defs.bzl and amalgamation under /upb/bazel. Those are utilities used in the build.
Move lua.BUILD and python* uner /python/dist. Those are used in the WORKSPACE dependency setup.
