rules_cc is incompatible with --incompatible_load_{cc,java,proto,python}_rules_from_bzl

[Yannic]

I think some (most) of these incompatibilities come from Protobuf.

The best solution would be to add rules_proto to the federation and update the dependency of the federation (the federation can't simply update to a compatible version of Protobuf because that version depends on rules_proto).

With https://buildkite.com/bazel/rules-cc-plus-bazelisk-migrate it will be easier to keep track of incompatible changes.
