Update Runfiles usage to fix BCR, bump versions

Fixes the runfiles problems with Windows builds for Bazel 8 and later
seen in bazelbuild/bazel-central-registry#5490. Bumps a number of
dependencies, and bumps the `rules_scala` version in `MODULE.bazel` from
`7.1.0` to `7.1.1`.

Dependency version bumps include:

- Go: 1.24.5 => 1.25.0
- `golang.org/x/tools`: v0.35.0 => v0.36.0
- `jline`: 3.30.4 => 3.30.5
- `protobuf-java`: 4.31.1 => 4.32.0
- `protobuf`: v31.1 => v32.0
- `rules_java`: 8.15.0 => 8.15.1
- `rules_python`: 1.5.2 => 1.5.3

Also:

- Restores `examples/crossbuild/protobuf.patch` to a symlink, undoing
  the change from bazel-contrib#1760.

- Fixes precompiled Windows protoc selection on ARM64 in
  `protoc/private/protoc_toolchains.bzl`.

- Removes `RULES_SCALA_MAIN_WS_NAME` from the ScalaTest runner
  implementation.

- Removes `rules_jvm_external` from `scala/latest_deps.bzl`.

---

bazelbuild/continuous-integration#2350 resolved the Windows symlink
problem, fixing the bazelbuild/bazel-central-registry#5490 Bazel 7
Windows build. This enables the restoration of the original
`examples/crossbuild/protobuf.patch` symlink, effectively closing
bazelbuild/bazel-central-registry#5506.

The `src/java/io/bazel/rulesscala/exe/LauncherFileWriter.java` changes
fix the remaining bazelbuild/bazel-central-registry#5490 breakages.
Specifically, adding the `.exe` suffix only when necessary under Bazel 7
fixes the Windows builds for Bazel 8 and later. However, we'll have to
close that pull request and push the v7.1.1 tag to begin a new release.

The updates to use `@AutoBazelRepository` and `Runfiles.preload()`, etc.
are from the `com.google.devtools.build.Runfiles` docstring:

- https://github.com/bazelbuild/rules_java/blob/8.15.1/java/runfiles/src/main/java/com/google/devtools/build/runfiles/Runfiles.java#L31-L134

`RULES_SCALA_MAIN_WS_NAME` is no longer necessary given proper runfiles
library usage, and technically became obsolete in commit
f758956.

Instantiating `rules_jvm_external` ourselves is no longer necessary
because `protobuf` v32.0 contains protocolbuffers/protobuf#22225, which
closed protocolbuffers/protobuf#19129.

I've tested this change using my personal Windows 11 ARM64 virtual
machine, hence the updates to `protoc/private/protoc_toolchains.bzl`.
Previously, the `exec_compatible_with` attribute of the toolchain target
contained `@platforms//cpu:x86_64` instead of `@platforms//cpu:aarch64`.
This caused `@protobuf//bazel/private:proto_toolchain_type` to resolve
to `@protobuf//bazel/private/toolchains:protoc_sources`, triggering
recompilation.

I also had to use `python.single_version_platform_override` and to fix
`@bazel_tools//tools/jdk:proguard_whitelister` on Windows ARM64. This is
because the latest `rules_python` 1.5.3 doesn't contain any entries for
`aarch64-pc-windows-msvc` in `//python:versions.bzl`.

However, it appears such entries are coming in the next `rules_python`
release, which will eliminate the need for such a workaround. For that
reason, I haven't tried to include it in this change.

A couple of interesting new facts I learned about `protobuf` in the
process of producing this change:

- v32.0 officially drops support for Bazel 6:
  https://github.com/protocolbuffers/protobuf/releases/tag/v32.0
  protocolbuffers/protobuf@da0077e

- v34 isn't dropping MSVC support after all:
