Allow unaffiliated users to use Crostini

If the policy is set to false, unaffiliated users will not be allowed to use Crostini.

If the policy is unset or set to true, all users are allowed to use Crostini as long as other settings also allow it.
All three policies, VirtualMachinesAllowed, CrostiniAllowed, and DeviceUnaffiliatedCrostiniAllowed need to be true when they apply for Crostini to be allowed to run.
When this policy is changed to false, it applies to starting new Crostini containers but does not shut down containers which are already running.

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
