Add protobuf_extra_deps.bzl for loading dependencies necessary for ex…

…ternal repositories in protobuf_deps.bzl. This is needed for `rules_java` which requires additional loads for Bazel 8. This provides a single entrypoint for extra dependencies so we can add these moving forward without breaking users, and is similar to https://github.com/grpc/grpc/blob/master/bazel/grpc_extra_deps.bzl. Non-bzlmod users should make sure to set the following in their WORKSPACE file: ``` http_archive( name = "protobuf", strip_prefix = "protobuf-VERSION", sha256 = ..., url = ..., ) load("@protobuf//:protobuf_deps.bzl", "protobuf_deps") protobuf_deps() load("@protobuf//:protobuf_extra_deps.bzl", "protobuf_extra_deps") protobuf_extra_deps(); ``` PiperOrigin-RevId: 700448687
