Capture more detailed EUM resource timings

Description

The Resource Timings API offers sometimes more detailed timings than we are currently fetching in the JS Agent, for example detailed DNS and fetch timings.
Additionally, these timings should enable us to detect if a resource was cached or not.
See https://developer.mozilla.org/en-US/docs/Web/API/Resource_Timing_API/Using_the_Resource_Timing_API for more information about the API.
