Aaron Klotz 2b62cb54a7 net/dns, util/winutil: improve detection of group policy affecting NRPT ...

Due to a customer issue, I investigated the Windows Dnscache service more
intensively. I learned that the only time it attempts to read the NRPT
from group policy is in response to a group policy change notification.

Under the hypothesis that policy refresh is not effectively delivering GP
notifications due to its dependency on reaching a DC, I replaced our use
of the RefreshPolicyEx with the quasi-documented GenerateGPNotification API.

Tests have been updated to ensure they check that they are running as
LocalSystem, which is required for GenerateGPNotification.

Fixes #20187
