Add logic to make sure that page sets paired with
smoothness/repaint only have interaction records with same label & they have repeatable flags enabled.

To make sure that this doesn't crash any smoothness
benchmarks, I modified benchmark_smoke_unittest to run all
smoothness benchmarks (including ones that only support
android) in patch #3. To validate the test runs, see
telemetry_perf_unittest's result in patch #5
