The migration to .bzl configured toolchains happened a long time ago and the conversion tools from proto files are not needed anymore.
This also cleans up rules_cc dependencies to build those tools. And unblock me around the import of py_proto_library, which is not needed anymore.

Simplify WORKSPACE setup and update ancient deps
By removing a single unused `bzl_library` target, rules_cc no longer has
any dependencies that would need to be loaded by a dependency macro. The
existing macro is made a no-op.
The few needed Bazel Federation dependencies are inlined and, in the
case of bazel_skylib and abseil-py, updated to modern versions.
Also reorders `WORKSPACE` to list direct dependencies first and keeps
`MODULE.bazel` in sync with the dependency versions used in WORKSPACE.
The `ubuntu1604` CI pipeline is removed as the version of Python used by
it is no longer supported and the distribution is EOL. Instead, a new
pipeline is added to check the Bzlmod build.

*** Reason for rollback ***
Broke a test
*** Original change description ***
The auto-configured toolchains provided by Bazel itself have diverged heavily from the version maintained in this repo. There is no need to maintain this duplication until Starlarkification has progressed succiciently for rules_cc to be the source of truth for them.
This is particularly relevant for Bzlmod, which currently uses the toolchains defined in rules_cc. As a result, Bazel C++ builds will use subtly different toolchains depending on whether --enable_bzlmod is used or not. This is fixed...

This is particularly relevant for Bzlmod, which currently uses the toolchains defined in rules_cc. As a result, Bazel C++ builds will use subtly different toolchains depending on whether --enable_bzlmod is used or not. This is fixed by loading toolchain detection logic from @bazel_tools in the module extension.

Instead, add an alias to the Bazel-provided runfiles library under //cc/runfiles, following https://bazel.build/rules/deploying.

This helps with getting rules_cc back to green. The distro package doesn't seem critical and it can be added back in a later CL once we figure out what is wrong with the rules_pkg dependency.

The cc_shared_library_permissions mechanism was introduced to add control over
which cc_shared_libraries can export a given cc_library. If the repo is big
enough, the owner of a cc_library might want to prevent someone else in a
different package making their library part of the ABI of a public shared
library because that makes it harder to change the cc_library. This does not
apply accross repositories because a dependant repository can overwrite
anything from a repository dependency anyway.
However, it is becoming more apparent than even though this mechanism should
exist, it should not be enabled by default since most people don't need it. To
enable it pass the flag --//examples:enable_permissions_check=True.

--//examples:incompatible_link_once=False[default = False]
When True, it will be an error to link the same library more than once
unless it has the tag LINKABLE_MORE_THAN_ONCE
--//examples:experimental_debug=True[default = False]
When True, it will generate files listing the exports of each cc_shared_library
and which libraries are linked to it statically.

We use BUILD example added in previous CL and inspect the resulting *.so files with nm.
Also fixes implementation of shared library to work with Bazel after having flipped the legacy whole archive flag. This caused exported libraries to be dropped by the linker unless they were alwayslink.
Still more tests to come.

This is only tested with Bazel at head. We modify the presubmits file so that we don't use release. The reason we don't use release is because we need very recent changes to Bazel to test cc_shared_library. In the future we will also test with release.
Also in following CLs, we will inspect in integration test the *.so output from these example builds to make sure that the correct symbols are linked statically and are visible.
After that we will add Starlark unit test to check error conditions.

Fixes:
* Enabled buildifier on the Bazel CI again
* Added Skydocs where missing
* Moved public files out of .../private/... (e.g. cc_toolchain_config_lib.bzl)
* Reformatted
* Removed unused loads
* Using relative labels for cc_configure related files
* Added development dependency on rules_proto
* they're not in the federation yet, so hand rolling in rules_cc's WORKSPACE file
* Added development dependency on rules_python (from federation)
* Cleaned up copybara (notable change - not using @rules_cc in labels inside rules_cc repo)
* Made cc_flags_supplier usable internally
* Moved load statements to the top of the bzl file
* Moved runfiles to the tools directory
* Unified toolchain_utils.bzl and find_cc_toolchain.bzl

We now have copies of .bzl files that we have to keep in sync between @rules_cc and @bazel_tools/tools
I propose to re-enable the Buildifier presubmit once this issue is resolved.
*** Original change description ***
Run Buildifier as part of the presubmit.
As a result we will catch some errors already in GitHub, and not later in Critique when it's harder to fix them.
