Provide both service state and status when possible in service_facts (#49618)

* Combine systemd units/unit-files output for service_facts

Fixes #47118

Previously we were only taking the output of `systemd units` which
would leave out information about the service units that were
disabled, static, masked, etc. Now we're aggregating the results so
that anything not active/inactive/dead at least is pulled as fact
data with it's state provided.
