Better results dispaly for new DeploymentStackWhatIfResult cmdlets

**Is your feature request related to a problem? Please describe.**
I am not fan of how the results coming from DeploymentStackWhatIfResult cmdlets are displayed. Now everything is displayed one line after another line without empty lines before the different resources. this makes it hard to read. Additionally now the full resource ID is displayed. This also makes it hard to read in CI/CD consoles like in Azure DevOps as you have to scroll horizontally to see the full value. The implementation for the regular WhatIfResult cmdlets was better from that perspective.

**Describe the solution you'd like**
Either go back to implementation of WhatIfResult cmdlets or do something like:

```
= Scope: /subscriptions/{subscription id}/resourceGroups/{resource group name}
= Resource: Microsoft.Storage/storageAccounts/{account name} [2025-06-01]
= Management Status: "managed"
= Deny Status: "none"

= Scope: /subscriptions/{subscription id}/resourceGroups/{resource group name}
= Resource: Microsoft.Storage/storageAccounts/{account name}/blobServices/default/providers/Microsoft.Insights/diagnosticSettings/LogsAndMetricsToLogAnalytics [2021-05-01-preview]
= Management Status: "managed"
= Deny Status: "none"

```

- two empty lines between different resources. Better to scroll vertically than horizontally.
- Scope and resource as separate entries. Reduces scrolling for long names.

**Describe alternatives you've considered**
