Remove reference to cc_proto_aspect

The symbol has been removed from Bazel 8, so any reference to it results in an error.

Using bazel_features, a bzl file with a reference is generated, based on Bazel version.

Protobuf 29.x doesn't have this problem because cc_proto_aspect wasn't exposed. But we should still cherry-pick exposing the aspect and this change to 29.x line, to make transition of rules_rust easier.

Closes: https://github.com/protocolbuffers/protobuf/pull/19576
