Build/Test Tools: Measure additional load time metrics in performance tests.

Three new metrics are being collected and reported as part of this change:

- Time To First Byte (TTFB) - the time between the request for a resource and when the first byte of a response begins to arrive
- Largest Contentful Paint (LCP) — the render time of the largest image or text block visible within the viewport
- The difference between the two (LCP minus TTFB)

Fixes #58360.
