Draft: Move L1 simulation to CA configuration

Move L1 simulation to CA configuration. Everything is there except:

1)NSW simulation (ATR-24631)

2)Floating point L1Calo simulation (except supercell emulation)

For 2), it wasn't clear to me who was using this at the moment - if it is definitely needed now, I can add it in, otherwise we can revisit this when needed. Question for @jmontejo, @blumen, @jburr, @bcarlson.

Cheers,

Stewart
