Include `ProductCode` in the winget manifest

[jiasli]

winget is requiring us to include ProductCode of the MSIs in Microsoft.AzureCLI's manifest (microsoft/winget-pkgs#123641 (comment)): https://github.com/microsoft/winget-pkgs/blob/master/manifests/m/Microsoft/AzureCLI/2.54.0/Microsoft.AzureCLI.installer.yaml

Three methods for extracting the ProductCode are provided: microsoft/winget-pkgs#123641 (comment)

If you use one of the popular manifest authoring tools to create the manifest, they will automatically add/update this field for you.

If you want to retrieve this for yourself, you can use a number of different methods:

• For installed MSI packages, you can get it by running the command (On PowerShell 5 / Windows PowerShell)

  get-wmiobject Win32_Product | Sort-Object Name | Format-Table IdentifyingNumber, Name -AutoSize
  

• If you have the .msi file, you can use something like MSI Viewer or some PowerShell scripting to retrieve the ProductCode.
• You can run the manifest in Windows Sandbox using the sandbox script and it will print out the related metadata for the package which includes the ProductCode

I am able to get the ProductCode with the first method on my Windows machine (even though Get-WmiObject Win32_Product is slow):

> Get-WmiObject Win32_Product | Sort-Object Name | Format-Table IdentifyingNumber, Name, Version -AutoSize

IdentifyingNumber                      Name                                                           Version
-----------------                      ----                                                           -------

{C56C2883-5C38-4789-B6BA-4D4B17440AE6} Microsoft Azure CLI (64-bit)                                   2.54.0

However, all these methods require either installing the MSI or other dependencies. As our automation bot @azclibot for generating the manifest is hosted on a Linux agent and the manifest generation logic is written in Bash syntax, these methods may not be practicable unless we move @azclibot to a Windows agent.

A workaround I can think of is to extract the ProductCode while building the MSI and save it to the built ADO artifact. Then use the ProductCode saved in the artifact to generate the manifest.

Regarding a fixed ProductCode

According to https://wixtoolset.org/docs/v3/xsd/wix/product/, Id of Product element is an AutogenGuid:

The product code GUID for the product.

So, in Azure CLI's Product.wxs, it is declared as

azure-cli/build_scripts/windows/Product.wxs

Line 36 in aeb94ed

<Product Id="*"

And according to https://learn.microsoft.com/en-us/windows/win32/msi/productcode

This ID must vary for different versions and languages.

It is not possible to have a fixed GUID. We must generate a new one for each MSI package.

Thank you for opening this issue, we will look into it.
