Fixing up the Microsoft.Net.Compilers.props file to place the ValidateMSBuildToolsVersion check in an InitialTarget.

Updating Settings.targets to ignore BC42366 and CS7035.

Enable release nugets

Simplify script to use nuget.exe for prerelease dependency validation instead of adding custom logic in the script for this.

This commit makes it so that we will always try to generate release nugets except if they depend on prerelease packages. If one of our nuget packages happens to depend on prerelease packages, then when building release nugets, we will simply print a message in the build output and skip release nuget generation for that package (and allow the overall build to succeed).

Updating VSL.Version.targets to properly specify build number.
