Add SearchPrewarmPrecisionOutcome UMA metric

Add PageLoad.Clients.GoogleSearch.PrewarmPrecisionOutcome to measure
the end-to-end lifecycle efficiency and precision of each DSE search
prewarm attempt.

This metric tracks whether each prewarm attempt ultimately benefited a
user navigation (via direct primary search process reuse, prerender
host reuse activation, or prerender fallback process reuse) versus
whether it was unused, cancelled, or failed before becoming ready.
