We don't generally use _ in the enum members.

(The main exception is when you just use 'Measure' in the IDL and it generates
e.g. V8CSSRuleList_Item_Method. We do have a few others... most of which are my
fault. Oops.)

Maybe just use [Measure] and use the autogenerated name?
(V8IDBObserver_Observe_Method)

Done.

     // Add new features immediately above this line. Don't change assigned
     // numbers of any item, and don't reuse removed slots.
