Prevent the build from succeeding if any errors are reported during the build process.
Without this flag, non-fatal errors, such as shader compilation issues on a particular platform, won't cause the build to fail, but might lead to incorrect behavior at runtime. When this flag is set, errors logged from build callbacks also fail the build, including these build callbacks: IPreprocessBuildWithContext.OnPreprocessBuild, IPostprocessBuildWithContext.OnPostprocessBuild, IProcessSceneWithReport.OnProcessScene, IPreprocessShaders.OnProcessShader, and IPreprocessComputeShaders.OnProcessComputeShader.
