Addresses the timeout-related part of #38782.

The object-detection example cancels its Dataflow job after a hard-coded 30-minute wait, while the benchmark workflow allows 180 minutes per step. This change adds --timeout_ms, keeps the 30-minute default, and sets the shared CPU/GPU batch/streaming benchmark options to 60 minutes.

This PR remains draft until a healthy run shows that 30 minutes is too short. The fixed-batch change in #39953 is upstream and may affect runtime. The recorded failure has repeated SDK harness disconnections before cancellation, so it does not establish healthy runtime. A later run failed during setup and skipped the benchmarks.

Python checks pass; end-to-end timing still needs the Dataflow benchmark infrastructure. Run the local Python unit suite with:

./gradlew :sdks:python:test-suites:tox:py312:testPython312

The failed Python 3.10 wheel job completed the build and auditwheel repair, then timed out during cibuildwheel's Docker cleanup. I did not find a build failure related to this change.

Could someone with rerun access retry that job? My fork account cannot rerun upstream Actions. Thanks!
