Add ability to select system mods in simulate

[Givikap120]

This is essential if you want to test specific ScoreV2 or Touchscreen scores

I've tried to avoid using reflection in tools since it's always a mess in terms of maintainence, but having system mods would be really useful. Do you think there's no other way of implementing this? Maybe somehow adding a non-system version of those mods locally or something?..

The only way to avoid reflection I see is making osu-lazer PR that will change accessibility to protected.
Because the problem is that there's just nothing you could do with the Mod Select (everything is private), unless you want to create entirely new Mod Select, copying all the code.
