1796639 - Add telemetry for first contentful paint keyed by TRR provider

Status: RESOLVED FIXED

(Core :: Networking, task, P2)

Description

[Andrew Creskey [:acreskey]]

One of the most meaningful measures of user experience is recorded in perf_first_contentful_paint_ms.
It would be useful to report this, keyed by TRR domain (or "native dns"), to ensure the user-facing performance is acceptable on all TRRs.

We are interested in the user-experienced performance based on the TRR (if any).
