[Build] Fix nuget pipelines to pass IsReleaseBuild to validate-package (#27387) ## Summary This PR fixes an issue where the is_release_build parameter was not being correctly passed to the validate_package.py script across various Azure Pipelines. ## Changes - Updated the combined CUDA packaging stage and its sub-stages to pass the IsReleaseBuild parameter through the template chain. - Added missing IsReleaseBuild parameter definitions to following templates: tools/ci_build/github/azure-pipelines/stages/nuget-linux-cuda-packaging-stage.yml tools/ci_build/github/azure-pipelines/stages/nuget-win-cuda-packaging-stage.yml - Ensured all calls to validate-package.yml (including the main CUDA NuGet stage) now explicitly pass the IsReleaseBuild flag. ## Context It is based on https://github.com/microsoft/onnxruntime/pull/27382.
