feat(metrics): Add default server.address attribute on server runtimes

[chargome]

Attaches a server.address attribute to all captured metrics on a serverRuntimeClient

Did this by emitting a new processMetric hook in core, that we listen to in the serverRuntimeClient. This way we do not need to re-export all metrics functions from server runtime packages and still only get a minimal client bundle size bump.

Added integration tests for node + cloudflare

JS-1178 Attach `server.address` as a default attribute to metrics

[Lms24]

I like the pattern. As discussed, we'll likely need a hook like this one for spans and logs as well, so this makes sense to me. Naming wise, we can still add (pre|post)ProcessMetric later on should we need it, so I think this is a good naming choice (and inline with the processEvent hooks on our Integration interface).
