linker bump breaks AOTing on iOS and Android when EnableAggressiveTrimming=true

[akoeplinger]

The linker bump in #49577 seems to break AOT when EnableAggressiveTrimming=true. This originally was found in Android.Device_Emulator.Aot.Test, but also applies to all test projects.

Can't find custom attr constructor image: /Users/alexander/dev/runtime/artifacts/bin/Android.Device_Emulator.Aot.Test/net6.0-Debug/android-x64/publish/Microsoft.DotNet.XHarness.TestRunners.Common.dll mtoken: 0x0a000064 due to: Could not load file or assembly 'System.Runtime, Version=4.2.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

Disabled the project temporarily.

@marek-safar not sure who should look into this, looks like System.Runtime.dll is getting trimmed out?

@MaximLipnin Please investigate

This problem should be now resolved and the test can be enabled.
