[telemetry] Make testMeasurementSmoke generate separate tests.

This way failures in one benchmark won't stop the rest of the tests, and it'll print separate GTest steps for each benchmark.
The test names follow the format BenchmarkSmokeTest.benchmark.name so you can still find BenchmarkSmokeTest with a search.

Also rename it to the more apt BenchmarkSmokeTest.
