Simplify trace test names. Originally we had a lot of conditionally enabled test configs in angle_perftests, that we enabled behind a flag because the total runtime would be too large if we left everything enabled. This CL switches to using a single test set, one for each trace, and using a the same command-line API we use in dEQP and the ANGLE samples to pick a single configuration. This makes it easier to pick exactly what configurations you want from the command line. Because we only run one configuration each time, we don't need to specialize the test name to include the configuration info. We can also simplify TracePerfTest -> TraceTest since these tests are run for both perf and correctness.
