Add GitVersion.Configuration.Tests project

This commit introduces the GitVersion.Configuration.Tests project in the solution. Several test files related to configuration were moved from GitVersion.Core.Tests to the new project, ensuring proper organization. Additionally, InternalVisibleTo attribute was added in GitVersion.Core and GitVersion.Configuration projects to include this new test project.
