Record service in telemetry events (#27252)

This change records the service name(s), if any, as part of the
SessionCreation/ProcessInfo events.
We cache the service names after the first time we calculate them in
order to avoid unnecessary overhead.

These changes enable deeper understanding of ORT usage, since multiple
services can run inside an application in svchost, which currently
obscures our understanding of which services/use cases are most popular.
Understanding which services are actually being used can help prioritize
more investments in making ORT better targeted to end users.

Have tested that the logic in GetServiceNamesForCurrentProcess can
accurately return service name for a given process
