Add Chrome DevTools Extensibility API

[tunetheweb]

Summary

The Chrome DevTools extensibility API adds some optional extra params to User Timing (performance.mark and performance.measure) and console.timestamp to provide additional information to performance traces.

I\m looking to document these in mdn/content#41372 and so adding BCD data here.

Test results and supporting details

User Timing supported from 128 - https://developer.chrome.com/blog/new-in-devtools-128#perf-extension
Console.timesstamp supported from 134 https://developer.chrome.com/blog/new-in-devtools-134#console-timestamp

Spec discussions:

• User Timing - Add a non-normative format for the detail param that allows developers to customize the presentation of timings in devtools w3c/user-timing#111
• Console.timesstamp - bocked on Spec console.timeStamp whatwg/console#140

Note I've marked it as "standard_track": false for now, since those discussions are ongoing.
