Adds a strong name key pair and signs all assemblies using the .snk file. Temporarily suppresses one warning until Spectre.Verify.Extensions is signed (in a separate PR).

Companion PR: spectresystems/spectre.verify.extensions#10

Once that merges and we update Spectre.Verify.Extensions in this repo, we can remove the NoWarn here:
https://github.com/KirillOsenkov/spectre.console/blob/6116af384458dc6acc7b887617e7aec45c703d86/src/Tests/Directory.Build.props#L8

I was also wondering why there's a separate Directory.Build.props in the Tests directory. All the three properties that it sets are already set by the parent. However the parent Directory.Build.props will not be automatically imported. If you want it to be imported you need to add: <Import Project="$([MSBuild]::GetPathOfFileAbove('Directory.Build.props'))" />
