[v3-3-test] Run lang-SDK K8s system test once in a dedicated job, not 6x per run (#69500)#69587

… 6x per run (apache#69500) The Multi-Lang KubernetesExecutor coordinator system test was gated on KubernetesExecutor + use-standard-naming==false, but that condition is true once per kubernetes-combo, so it ran redundantly across all six Python/K8s combos on ci-amd (and again on ci-arm) - adding ~4 minutes of Go/Java build and coordinator run to each of those six system-test jobs and pushing them to ~20 minutes, well above the rest of the matrix. The test is executor/naming/version-independent, so run it once instead: a dedicated tests-kubernetes-lang-sdk job on a single default Python-Kubernetes combo that provisions the native Go/Java toolchains (cached) and runs only the lang-SDK test (-k test_lang_sdk_combined_dag_succeeds), not the full suite or the upgrade path. The regular system-test matrix no longer runs it at all, so those six jobs drop back to ~15 minutes. Also scope the Go/Java build caches by runner.arch: the previous key used only runner.os (Linux), which would collide between amd64 and arm64 runners now that the dedicated job runs on both.
