runtime: Regression on static initialization using STJ

Can be reproduced on the build after these changes: https://github.com/dotnet/runtime/compare/2d552be28782f3ff7e50c90d272c1b77d5c7db16...7efce05745322d722e3effac4f0859c554ad7ec0

With this code in a static class:

private readonly static uint _jsonPayloadSize = (uint)JsonSerializer.SerializeToUtf8Bytes(new JsonMessage { message = "Hello, World!" }, SerializerOptions).Length;

The following exception is thrown at runtime:

Unhandled exception. System.TypeInitializationException: The type initializer for 'PlatformBenchmarks.BenchmarkApplication' threw an exception.
 ---> System.TypeInitializationException: The type initializer for 'System.Text.Json.JsonSerializerOptions' threw an exception.
 ---> System.InvalidOperationException: Could not execute the method because either the method itself or the containing type is not fully instantiated.
