Add Preview build configurations to solution

Added 'Debug Preview' and 'Release Preview' build configurations for every project in the solution. These custom configurations will allow us to test features and optimizations before they are finalized for a release configuration. The addition supports more flexibility and accuracy in the pre-release testing phase.
