This PR reduces metrics bundle size by converting the MetricsInstrumentation class into a set of functions.

The MetricsInstrumentation class constructor was turned into the startTrackingWebVitals function. The internal class state was turned into a set of global variables that get mutated.

Resolves https://getsentry.atlassian.net/browse/WEB-816
