On-device tests which run the same project but with different runtimes must use different package names or we might find ourselves in a situation when an application built for a different runtime and installed over a previous version which uses another runtime, won't even start. This happened with NativeAOT in the InstallAndRunTests.DotNetRun test.

This pull request introduces improvements to how Android runtime variants are handled in device integration tests. The key change is to parameterize tests by
AndroidRuntime, ensuring that each runtime uses a unique package name and configuration. This prevents cross-runtime interference and enables broader test coverage. Additionally, a utility method is introduced to standardize package name generation.Test parameterization and runtime handling:
Major device integration tests (
LocalizationTests,TimeZoneInfoTests,SystemApplicationTests,UncaughtExceptionTests,MonoAndroidExportTest, andMarshalMethodsGCHangTests) are updated to run against allAndroidRuntimevalues using[Values]or[TestFixtureSource], with appropriate handling for unsupported configurations and unique per-runtime package names.Tests now set the runtime explicitly on
XamarinAndroidApplicationProjectand related objects, and adjust build configurations such asIsReleaseandSupportedOSPlatformVersionbased on the runtime.Utility and infrastructure improvements:
A new
PackageUtils.MakePackageNamemethod is added to generate unique package names per runtime, and is used throughout the updated tests to avoid conflicts.Test project creation and setup now use the test name and runtime to ensure isolation and reproducibility.
Test codebase maintenance:
Xamarin.Android.Tasksare added to relevant test files to support the new runtime and package utilities.These changes collectively improve test reliability and coverage across different Android runtime implementations.
