Enable more tests to run on all 3 runtimes, part 11

[grendello]

This pull request expands test coverage across multiple test classes to ensure all tests are executed for every supported AndroidRuntime (MonoVM, CoreCLR, NativeAOT). It does so by parameterizing tests with the AndroidRuntime enum, updating project initialization to reflect the runtime, and adding runtime-specific configuration and skip logic where necessary. This ensures that features and behaviors are validated across all runtime variants, improving reliability and future-proofing the test suite.

Key changes include:

Test Parameterization and Runtime Handling:

• Parameterized numerous [Test] methods across AndroidResourceTests, CheckClientHandlerTypeTests, LinkerTests, ManagedResourceParserTests, and ResolveMonoAndroidSdksTests to run with all values of the AndroidRuntime enum using [Values] AndroidRuntime runtime.

• Updated project creation in tests to set IsRelease based on the runtime (e.g., NativeAOT implies release), and called SetRuntime(runtime) on test projects to ensure correct configuration.

• Added runtime-aware skip logic using IgnoreUnsupportedConfiguration(runtime, release: isRelease) to bypass incompatible test configurations.

Test Data and Behavior Adjustments:

• Refactored test data sources to generate cases for all AndroidRuntime values, ensuring comprehensive coverage.

• Adjusted test logic and assertions to handle differences in build outputs and behaviors between runtimes, particularly for NativeAOT (e.g., output directory structure, test skips for known issues).

Miscellaneous:

• Added necessary using directives and minor code cleanups to support new logic.

These changes collectively ensure that the test suite robustly validates Xamarin.Android behavior across all supported runtime environments.

I merged in main, which should hopefully resolve the timeouts that were there before.
