[mobile] Enable NativeAOT library tests on Apple mobile platforms#125437

Conversation
Replace NativeAOT runtime test legs with library test legs on iOS/tvOS devices, iOS/tvOS simulators, and Mac Catalyst. The runtime tests (nativeaot/SmokeTests) provide minimal value on mobile since the compiler doesn't meaningfully distinguish between iOS and macOS. Library tests exercise OS-specific APIs (crypto, networking, etc.) that are the real quality gate. Changes: - ioslike: remove NativeAOT runtime test leg, update existing library test leg to use dynamic smoke test arg - ioslikesimulator: replace NativeAOT runtime test leg with library test leg, fix isiOSLikeSimulatorOnlyBuild parameter - maccatalyst: replace both NativeAOT runtime test legs (regular + AppSandbox) with library test legs, fix coreclrContainsChange variable (was incorrectly using monoContainsChange) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
This PR updates the Apple “extra platforms” CI legs to validate NativeAOT on iOS/tvOS devices, iOS/tvOS simulators, and Mac Catalyst by running libraries tests (via Helix) instead of the minimal NativeAOT runtime SmokeTests, improving OS-specific coverage (crypto/networking/globalization) on mobile.
Changes:
- Switch NativeAOT Apple-mobile legs from runtime SmokeTests submission to
eng/pipelines/libraries/helix.ymlsubmission of libraries tests. - Use
eng/pipelines/libraries/helix-queues-setup.ymland passNeedsToBuildAppsOnHelix=truefor the new legs. - Update naming/args to use
$(_runSmokeTestsOnlyArg)and fix path-evaluation variable naming in affected legs.

Description
Enables NativeAOT library tests on Apple mobile in extra platforms by wiring the trim+ILC step on the host build leg and consuming the produced static library in
AppleAppBuilderlibrary mode on the Helix.Build flow
NativeLib=Static+CustomNativeMain=true, producinglib<TestAssembly>.aplus the staged ILC link inputs.eng/testing/tests.ioslike.targetsis updated to setTestNativeAot/TestSingleFile/PublishAotUsingRuntimePackand to opt into_SuppressNativeLibEventSourceWarningfor the static-library path.src/mono/msbuild/apple/data/ProxyProjectForAOTOnHelix.projno longer re-runs ILC on the agent. It detects the prebuilt static library via the new_NativeAotLibraryTestOnHelixproperty, replaces_AppleNativeAotCompilein$(AppleBuildDependsOn)with_StageNativeAotLinkInputsOnHelix, and unconditionally addsDirectPInvoke __Internalso the AppleAppBuilder-generated objc symbols (mono_ios_set_summary, …) are statically resolved by ILC.Pipelines
