We should make collecting metrics easier by adding an IDL attribute
https://bugs.webkit.org/show_bug.cgi?id=96837
Reviewed by Kentaro Hara.
Currently it is too hard to set up a good measurement experiment to see
whether we can safely remove a feature (including vendor-prefixed
features). This patch introduces the [V8MeasureAs] IDL attribute to make
that process easier.
When you add the [V8MeasureAs] IDL property to an API, we'll count what
fraction of Page objects used that API.
