…rrors (#56659) ## Summary Improve `dotnet test` device-selection failures to identify the project and target framework that failed, while preserving the selector's original error. Do not change device selection or normal all-target-framework execution. For example: ```text No devices are available for this project. Device selection failed for project 'MauiTestRc2.csproj' (target framework 'net11.0-ios'). ``` Projects without a target framework receive a project-only diagnostic. Includes regression coverage, regenerated localization, and clarification of multi-target device behavior in the existing MAUI run/test specification. ## Problem `SelectDeviceForTfm` reported every failed device selection as a multiple-devices error, even when no devices were available. In a project targeting Android, iOS, and Mac Catalyst, selecting an Android device could succeed and then device selection for iOS could fail. The resulting error incorrectly suggested the Android device selection was still ambiguous and did not identify the failing framework. This was reproduced interactively with .NET 11 RC 2 on Windows: selecting Pixel 5 among four connected Android devices succeeded, then iOS discovery returned no devices because `IsMacEnabled` was false. Android-only execution, including plain `dotnet test` on a project with only the Android entry in `TargetFrameworks`, succeeded.
