Remove direct references to system_python.bzl in favor of using protobuf_deps.bzl instead. Use python/dist/system_python.bzl where it was moved in v5.27.0 if you need a direct reference.

Rename bazel_osx_p4deps to for_bazel_tests. The name was used in the past.
Fix all bzl_libraries to have the correct set of dependencies.
Cleanup for_bazel_tests to include BUILD file and public bzl_libraries in the package.

The rules in protobuf and built-in Bazel don't mix well. Different aspects may cause actions conflicts. The safest way is to use built-in rules whenever they are still present.
proto_library should be safe, because it's not using an aspect. py_proto_library never had a built-in implementation, so it's also safe.
This still makes it possible to use the rules on Bazel 7, but only with --incompatible_autoload_externally enabled.

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.

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.

This CL is mostly a no-op, except that now google3-only code is actually stripped from OSS, instead of being preserved in `# begin:google_only` blocks.
This follows the conventions of the greater Copybara ecosystem.

This simplifies upb by removing differences between google3 and OSS.
This also points upb at the protobuf license, instead of keeping a separate copy around for upb.

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.

Rewrite compile tests from BazelProtoCommonTest to Starlark. This is using rules_analysis for testing.
The tests are super fast (cca. 1s for all of the to run).
The tests work either with a redirect (calling native rule) or with actual implementation in the protobuf repository.

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.
