Add Set time and date automatically config profile (#49468)

This enforces NTP on macOS devices.

The "Set date and time automatically" toggle can be verified with
`systemsetup - getusingnetworktime` (you can write a script to put the
output of that into a file, then use the `file_lines` table in a
policy), and set with `systemsetup - setusingnetworktime on` (which
could be a script automation that kicks off if a device fails the
policy).
If you want to prevent users from changing it, you can use the attached
config profile. Note that it requires setting the NTP server, but this
is most likely just the default Apple server. The `setusingnetworktime`
will work even with the Ul locked.
