System.Reflection.Metadata.ApplyUpdateTest.TestAddInstanceField fails after roslyn update in hotreload-utils

Start with the failing TestAddInstanceField case in src/libraries/System.Runtime.Loader/tests/ApplyUpdateTest.cs at line 389 and the AddInstanceField constructor in AddInstanceField.cs at line 42. Compare the Roslyn update from PR 115709 with the Mono interpreter path in RuntimeHelpers.Mono.cs at line 19, then run the test in the affected Mono cases. Done means the test passes and no longer needs to remain disabled for dependency flow.

https://github.com/dotnet/runtime/pull/115709 updated roslyn in hotreload-utils and we started seeing this test failure in Mono interpreter cases:

Disabled the test for now to unblock the dependency flow.
