Allow EnrollmentState to be in status '3' for MDM clients (#17868)

#17692

Recently there was a change that filtered out hosts in `EnrollmentState`
3. This change may cause some hosts that are in otherwise good health to
appear unresponsive to MDM in the management UI.

This change will allow hosts with `EnrollmentStatus` 3 show as enrolled.

The root cause of some hosts being in state 3 is still not entirely
clear, but may have to do with either trying to re-enroll once already
enrolled, or windows updates causing some sort of issue with fleet.

Despite the "failed" `EnrollmentState` 3, the host will still display
that the system is managed by Fleet, and will actively sync.
