Make Powershell completion script work in constrained mode

Browse source 
Creating CompletionResult objects is not allowed in Powershell constrained mode, so return results as strings if constrained mode is enabled

Store results as PsCustomObjects instead of hashtables. This prevents Sort-Object from trying to convert the hashtable to a object, which is blocked in constrained mode.
PsCustomObjects are created using New-Object to work around https://github.com/PowerShell/PowerShell/issues/20767
