[iOS/tvOS] Small set of test suites time out on devices

[steveisok]

The following test suites time out on CI and need investigated. Initial analysis shows that many tests pass, but it may be hanging on a single test. To find out which one, that requires an xharness tweak at https://github.com/dotnet/xharness/blob/3bf4d1484d4975ac382365262a93f29957ebe725/src/Microsoft.DotNet.XHarness.TestRunners.Xunit/iOSApplicationEntryPoint.cs#L46

• Microsoft.Extensions.DependencyInjection.ExternalContainers.Tests
• System.Net.NetworkInformation.Functional.Tests
• System.Reflection.Tests
• System.Threading.Channels.Tests

I believe the cause may be due to slow macs not being able to get through enough of the build before it times out. The size of the listed apps are rather large. To get this under control, we would need to enable aggressive trimming. That will take some time making sure the tests check out properly, so moving to .NET 8.
