test: CoreCLR iOS integration tests

[Flash0ver]

Summary

Enable iOS integration tests to also run on CoreCLR, alongside Mono.

Remarks

.NET 10 has added experimental opt-in support for CoreCLR on Android, and is scheduled to make it the default for .NET 11, while keeping Mono an opt-in.

.NET 11 (currently in Preview) is adding experimental opt-in support for CoreCLR on iOS.

In #5127, we added CoreCLR (alongside Mono) integration tests for Android.
In #5126, we have prepared the iOS integration tests to use CoreCLR too, once we start using .NET 11 (Preview).
