Remove test that sets static readonly field after type initialization #33413

dotnet/coreclr#20866 extends the jit to incorporate the type of readonly ref
class typed static fields into jitted code when jitting happens after class
initialization. For instance, the jit may optimize type tests or devirtualize
calls.

With the advent of type based jit optimizations we are also blocking reflection
based updates to all readonly static fields after class initialization.

Func<PropertyAndFields> func = assignToReadonly.Compile(useInterpreter);
func();
Assert.Equal("ABC" + useInterpreter, PropertyAndFields.StaticReadonlyStringField);
}

I assume both the false and true variants of this test fail now (by design) with your change?

Unfortunately, no ... the compiled version will still "succeed."

There are number of other discrepancies between interpreted and compiled expressions if the expression is invalid. This is just one more.

They should be made consistent if there isn't a very good reason otherwise. I'll hopefully get back into contributing later this year, and I'd be interested in doing it then, but I'm by no means grabbing it if anyone else is interested.

CI showing some flaky failures. Any point in retrying them...?

Since this is just deleting a test, no need. Thanks.
