Bind Xamarin.AndroidX.Compose.Foundation MutationInterruptedException

[Copilot]

androidx.compose.foundation.MutationInterruptedException — the exception Compose throws into await-able state-mutation APIs (e.g. ScrollState.animateScrollTo, LazyListState.animateScrollToItem) when a higher-priority MutatorMutex caller wins mid-flight — was silently dropped during binding, forcing C# callers to over-catch with Java.Lang.Throwable.

Root cause

Although both MutationInterruptedException (public final) and its parent internal.PlatformOptimizedCancellationException (public abstract) are public in the JAR, class-parse misreads the Kotlin metadata and emits visibility="private" for both, so the generator drops them. The parent was never bound either (only its _jvmAndAndroidKt helper), leaving the subclass without a chainable base type.

Changes

• foundation-android/Transforms/Metadata.xml: add <attr name="visibility">public</attr> for both MutationInterruptedException and internal.PlatformOptimizedCancellationException, restoring the parent base type so the subclass binds naturally.
• PublicAPI.Unshipped.txt: add the surfaced types/members (parent class + 4 ctors, child class + ctor, and their override accessors).
• config.json: bump Xamarin.AndroidX.Compose.Foundation / .Android nugetVersion 1.11.2.1 → 1.11.2.2.

Both target namespaces already exist in published-namespaces.txt, so no namespace changes were needed.

This lets callers catch the exception by type:

try
{
    await scrollState.AnimateScrollToAsync(targetValue, ct);
}
catch (MutationInterruptedException)
{
    // gesture or higher-priority mutation won; ignore
}

Pull request overview

This PR fixes a Compose Foundation binding gap where androidx.compose.foundation.MutationInterruptedException (and its base androidx.compose.foundation.internal.PlatformOptimizedCancellationException) were being dropped due to mis-read Kotlin metadata visibility, preventing C# consumers from catching the exception by type.

Changes:

• Forces both exception types’ visibility to public via foundation-android Metadata.xml so they are emitted by the generator.
• Updates PublicAPI.Unshipped.txt to reflect the newly surfaced public surface area.
• Bumps the NuGet revision for the Xamarin.AndroidX.Compose.Foundation and .Android packages to publish the binding change.
