Optimization: Modernize Create-ImageVirtualDisk using native PowerShell cmdlets

[msancaktutan]

Description:
This PR optimizes the Create-ImageVirtualDisk function to improve reliability, performance, and modernization of the codebase.

Changes:

• Replaced Regex parsing: Switched from parsing physical drive strings (which can be risky on different hardware) to using Get-DiskImage | Get-Disk for 100% accurate disk detection.
• Removed external dependency: Replaced the legacy format.com call with the native Format-Volume PowerShell cmdlet for faster execution and better error handling.
• Added Retry Logic: Implemented Execute-Retry during disk detection to handle potential OS delays when attaching VHDs.
• Code Cleanup: Improved logging and resource cleanup (closing handles).

Tested on Windows Server 2016/2019/2022/2025

Oh, you mean that you created Windows image for Windows Server 2016, 2019, 2022, and 2025? or you tested that the code still works on Windows Server 2016, 2019, 2022, and 2025 Hyper-V hosts?

I used Windows 11 as my host machine to run the script, and successfully created the guest images for Windows Server 2016, 2019, 2022, and 2025.
