13630176 - Derive ORT_TEST_VERBOSE from System.Debug via runtime coalesce in plugin test pipelines (#28517)

Derive ORT_TEST_VERBOSE from System.Debug via runtime coalesce in plugin test pipelines (#28517) ## Summary Five plugin test stage YAMLs reference `$(System.Debug)`, a predefined ADO variable that is only set when "Enable system diagnostics" is checked at queue time. When undefined, two failure modes occur: - **bash command lines** (Linux WebGPU/CUDA stages): bash interprets `$(System.Debug)` as command substitution and the step fails with `bash: line 14: System.Debug: command not found`. - **YAML `env:` blocks** (Mac/Win WebGPU + Win CUDA stages): the env var is set to the literal string `$(System.Debug)`, meaningless to test code that expects `true`/`false`/`1`/`0`. ## Fix Add a derived pipeline-level variable to the two test pipeline entry points: ```yaml # Verbose-output flag for tests. Resolves to System.Debug when set # (e.g. queue-time "Enable system diagnostics"), else 'false'. - name: OrtTestVerbose value: $[ coalesce(variables['System.Debug'], 'false') ] ``` and switch the five stage references from `$(System.Debug)` to `$(OrtTestVerbose)`. This avoids redefining the predefined `System.Debug` variable while preserving the "Enable system diagnostics" UI toggle — when that checkbox is set, `System.Debug` is `'true'` at runtime and the derived variable follows. A compile-time `${{ if }}` template alternative was not used because template expressions are evaluated at compile time and cannot see queue-time runtime variables like `System.Debug`; only a runtime expression (`$[ ]`) can react to the standard system-diagnostics checkbox. ## Files changed | File | Change | |---|---| | `plugin-webgpu-test-pipeline.yml` | Add `OrtTestVerbose` derived variable | | `plugin-cuda-test-pipeline.yml` | Add `OrtTestVerbose` derived variable | | `stages/plugin-linux-webgpu-test-stage.yml` | `$(System.Debug)` → `$(OrtTestVerbose)` | | `stages/plugin-linux-cuda-test-stage.yml` | `$(System.Debug)` → `$(OrtTestVerbose)` | | `stages/plugin-mac-webgpu-test-stage.yml` | `$(System.Debug)` → `$(OrtTestVerbose)` | | `stages/plugin-win-webgpu-test-stage.yml` | `$(System.Debug)` → `$(OrtTestVerbose)` | | `stages/plugin-win-cuda-test-stage.yml` | `$(System.Debug)` → `$(OrtTestVerbose)` | Pipeline run verified ✅ Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
