This patch adds a perf test harness for Dawn and a simple test of buffer upload performance. The test harness is based off of ANGLE's perf tests. Because perf tests are parameterized to support multiple test variants, this patch also adds DawnTestWithParams and ParamGenerator to support instantiating tests with additional parameters.
