Azure Split - Step 1 - Prep Work

[paulmedynski]

Description

This PR contains a variety of prep work that sets the stage for the addition of the Abstractions and Azure packages:

• Lots of pipeline changes and cleanup to make it smoother to add the Abstractions and Azure packages to the mix.
• Some cleanup adjacent to where the Azure code will be moved out of MDS.
• Some improvements that were made along the way for general clarity or consistency.

I have added commentary around the interesting changes. This is probably the largest and most complex PR of this series.

PR series:

• Azure Split - Step 1 - Prep Work #3902:
  • Merge changes that aren't directly related to the Azure split work, but that set the stage for that work.
• Azure Split - Step 2 - New Files #3904:
  • Merge new files and related changes that do not affect the existing MDS projects or artifacts.
• Azure Split - Step 3 - Tie Everything Together #3908:
  • Merge the changes to MDS and pipelines that tie everything together.
• Azure Split - Step 4 - Cleanup #3917:
  • Any remaining tasks or cleanup.

Testing

• Normal PR/CI pipeline runs will validate most changes.
• Manual inspection of pipeline logs and artifacts will confirm some of the fiddly parts.

Pull request overview

This PR represents "Step 1" of an Azure component split initiative, focusing on common infrastructure changes needed to support future modularization. The changes primarily refactor the build system, update pipeline configurations, and improve code quality without introducing functional changes to the driver itself.

Changes:

• Refactored NuGet package generation by splitting monolithic targets into separate files for MDS, AKV, and SqlServer packages
• Renamed and reorganized build properties (e.g., NugetPackageVersion → mdsPackageVersion, AssemblyFileVersion → mdsAssemblyFileVersion) to support multiple package versioning
• Converted pipeline template paths from relative to absolute for better maintainability
• Improved code quality with nullable annotations, property encapsulation, and defensive null checks
• Updated test infrastructure to support both Project and Package reference types more cleanly
