Enhance performance timings with the DevTools extensibility API

[nolanlawson]

Chrome DevTools has a new API where you can extend information from performance marks/measures to do a few things:

1. Have a separate track from other perf marks/measures (e.g. for a specific JS framework)
2. Add details on hover or click

I think #1 is a no-brainer that we should do. For #2 it might be interesting to add details like a list of property mutations that caused a re-render.

The Angular and React usages are good sources of inspiration: angular/angular#55805 facebook/react#29231

Relevant code for us:

lwc/packages/@lwc/engine-core/src/framework/profiler.ts

Line 70 in 16697a5

performance.measure(measureName, markName);
