Subject: [PATCH] Fine tune the number of test jobs running in parallel to
 avoid timeout on Intel macOS platform

After https://github.com/bazelbuild/continuous-integration/pull/1600, Bazel CI sets the default value of --local_test_jobs on macOS x86_64 platform to 18, which caused many tests to timeout: https://buildkite.com/bazel/bazel-bazel/builds/23062
