[wptrunner] Collect per-test trace events from Chromium

When wpt run --trace-categories is specified, the trace events are retrieved from an internal ChromeDriver buffer and logged as an extra test result field. The trace will be consumed by an event listener on the Chromium side (https://crrev.com/c/6820247) and can be viewed in https://ui.perfetto.dev/.

Partially fulfills https://crbug.com/434017035
