Split core simulation into multiple functions

[rigelrozanski]

Followup to #2736 (comment)

within simulation (x/mock/simulation/simulation.go) there is a "master" simulation function SimulateFromSeed - this function is ~200LOC and should probably be broken up into 3-5 functions for better code comprehension, I imagine the contents of that giant loop should be broken out for example.

That’s the case for the simulation module correct (I believe there’s a TODO). We should leave mock as is bc we want to deprecate it in the future
