refactor: remove protobuf_workspace

[thesayyn]

• removes protobuf workspace
• removes dependency on protobuf repository.

currently, there are no prebuilt binaries available, it's built from the source using the protobuf workspace. Will add the toolchain for prebuilt binaries in a follow-up

RELNOTES[INC]: protobuf_repo was removed

[fowles]

quick heads up that I renamed the branch master to main, so you may need to kick this a bit if something goes funny there

Please also fix CI failures.

In case you can't access them, let me know. The failures are:

run the following command in your workspace:<br/><pre><code>buildifier MODULE.bazel WORKSPACE dev_deps.bzl proto/BUILD proto/private/BUILD proto/private/versions.bzl</code></pre>

Beware that there are tests that depend on protobuf repo. should I remove those as well?

Could you add a dev dependency to protobuf repo and update the test so that it uses sources?

https://github.com/bazelbuild/rules_proto/pull/181/commits/19dbb3fe7a51c77b812d6c514948222723b39eec can I take this change back then?

Yes, please do. Sorry for the trouble

@comius PTAL.

There's still a buildifier warning, please run buildifier MODULE.bazel WORKSPACE dev_deps.bzl

Friendly ping.

Please also remove the toplevel BUILD file. I'll create that one in a separate PR, that follow licensing guidelines. (ATM that file breaks copybara)
