[APM] Experimental Service Map front end (elastic#46497)
Add service map tabs on the main APM screen and for individual services. This is not yet hooked up to work with back-end data, so it always shows the same hard-coded graph. This is experimental, so you must have x-pack.apm.serviceMapEnabled: true in your Kibana config for it to show up. Also add "PSF" to the list of allowed licenses since a new dependency added uses this license (it's on the [green list](https://github.com/elastic/open-source/blob/master/elastic-product-policy.md#green-list).) Fixes elastic#44890 Fixes elastic#44853
