[RUM Profiler] send view names as event attributes

[thomasbertet]

Motivation

We want to allow filtering by view name in the Profiling explorer (ie. @view.name:/my-view).
In order to make the view name query-able, we need to pass it as the event's attributes (just as we do for view ids)

Changes

• new view.name attribute in the Profile's event.json sent to intake.

Test instructions

• Browse a website with this version of the SDK, with the RUM Profiler active.
• After a while (tipically a minute of navigation), assert you can see a call the the profile intake.
• Assert you can see the event.json sent includes the new view.name attribute.
• Go over the Profiling's Explorer page
• Filter using the search bar to @view.name:<the-view-you-were-browsing> and you should see a Flame Graph.

🔗 RealWorld

[BenoitZugmeyer]

question: view ids were de-duplicated. It's not needed anymore?

[thomasbertet]

I believe it's not needed yes. I don't see how we could generate duplicated ids 🤔
