Web Vitals is an initiative by Google to provide unified guidance for quality signals that are essential to delivering a great user experience on the web. https://web.dev/vitals/ Instead of a manual implementation targeting the performance API directly, this commit adds metrics by using the web-vitals library. Using web-vitals allows us to easily report on all supported metrics at the cost of ~1kb in the minified @sentry/apm bundle.
