Replace assert in Precode::SetTargetInterlocked (#20007)

Fixes https://github.com/dotnet/coreclr/issues/19954
- `SetTargetInterlocked` can be soon followed by `ResetTargetInterlocked`, so the assert at the end of `SetTargetInterlocked` is invalid
- Removed the assert and instead just verified that the specified target is not the default prestub target
