bazel: Upgrade rules_java to 9.1.0 in WORKSPACE to support JDK 25

The WORKSPACE build pinned rules_java 8.15.2, whose newest bundled JDK is
21. Bazel's default --java_runtime_version is local_jdk, so on a host whose
default JDK is newer than 21 the javac toolchain cannot target it and the
build fails:

  error: [BazelJavaConfiguration] The Java 21 runtime used to run javac is
  not recent enough to compile for the Java 25 runtime in external/local_jdk.

This started failing in CI when GitHub's ubuntu-latest runner image moved
from Ubuntu 24.04 (default JDK 17) to 26.04 (default JDK 25). The bzlmod
build was unaffected because MODULE.bazel already uses rules_java 9.1.0.

Upgrade the WORKSPACE build to the same rules_java 9.1.0. Since 8.16,
rules_java_deps.bzl loads @bazel_features, so bazel_features_deps() must
now run before rules_java_dependencies(). examples/ has its own WORKSPACE,
so apply the same change there.
