Pull request overview

This PR fixes the computation of _LibMonoLinkMode when not using the Mono runtime, ensuring that static libraries are used for device builds with NativeAOT. The change corrects the MSBuild logic to properly handle different runtime types (MonoVM, CoreCLR, NativeAOT) and platforms.

  • Refactored _LibMonoLinkMode computation to properly handle NativeAOT and CoreCLR runtimes
  • Updated logic to enforce static linking for iOS/tvOS device builds (except temporary CoreCLR exception)
  • Updated test expectations to reflect smaller app bundle size due to static linking

File Description
dotnet/targets/Xamarin.Shared.Sdk.targets Refactored _LibMonoLinkMode conditions to properly differentiate between MonoVM, CoreCLR, and NativeAOT runtimes, ensuring static linking on device builds
tests/dotnet/UnitTests/expected/iOS-NativeAOT-size.txt Updated expected app bundle size to reflect removal of dynamic libraries (.dylib files) in favor of static linking, reducing total size from 3.8 MB to 2.5 MB
