[i18n-activity] [user-timing] Use WHATWG/INFRA is definition for (#1392)

himorin has just created a new issue for https://github.com/w3c/i18n-activity:

== [user-timing] Use WHATWG/INFRA is definition for  ==
User Timing Level 3 / section 4.1 Convert a mark to a timestamp
https://w3c.github.io/user-timing/#convert-a-mark-to-a-timestamp

In step 2., spec states

> Otherwise, if mark is a DOMString, let end time be the value of the startTime attribute from the most recent occurrence of a PerformanceMark object in the performance entry buffer whose name matches the value of mark. If no matching entry is found, throw a SyntaxError.

which uses a text `whose name matches the value of mark` over user defined DOMString value. To use clear state, this text could refer [`is` in WHATWG/INFRA](https://infra.spec.whatwg.org/#string-is) instead of just `matches`.


request `s:` label for user-timing spec. (seems missing; no item found with "timing")
