Pull request overview

This PR upgrades a set of snippet projects under System.Runtime*-related APIs to target .NET 10, aligning snippet compilation with newer TFMs as part of the broader cleanup/modernization work tracked in #12513.

Changes:

• Update many C# snippet .csproj files from net6.0 (and a couple from net48/net481) to net10.0.
• Preserve Windows-specific targeting by moving net6.0-windows to net10.0-windows where applicable.
