Show the value of P4ROOT

All Platforms	Windows only
If the server is running, the p4 info command shows the value of `Server root` directory.	Whether the server is running or not, the Windows user who is the Windows administrator can see the value of `P4ROOT` in the output of `p4 set -S Perforce` where Perforce is the service name associated with the Helix Core Server. In addition to the service name, a Windows service also has a display name. In older versions, such as 2017.1, the display name was also `Perforce`, but recent versions have `Helix Core Server` as the service display name.
