Begin Bazel 8/rules_java 8 compatibility updates

These changes enable both `WORKSPACE` and Bzlmod builds to reach a point
where both fail with the following errors. Part of bazel-contrib#1652.

- To use `WORKSPACE`, specify `--enable_workspace --noenable_bzlmod` on
  the command line or add them to `.bazelrc`.

Per that issue, the following breakages may be resolved by a new
`protobuf-java:4.29.0` release (without the `-RC3` suffix. Then we can
try to run the rest of the `rules_scala` test suite.

Also per that issue, adopting Bazel 8 and rules_java 8 compatibility
will necessarily break Bazel 6 and 7 compatibility.

---

Hoisted the `load_rules_dependencies()` macro into the new
`//scala:deps.bzl` file to avoid copying everything into `WORKSPACE`.
Changed the order of `http_archive()` calls as well. Without importing
these repos in this order, the build would break under `WORKSPACE`.
Without the `rules_java_dependencies()` and `protobuf_deps()` calls
where they are, the build also breaks.

---

Under both `WORKSPACE` and Bzlmod, the following build command will fail
with a `mismatched Protobuf Gencode/Runtime version suffixes` error:
