imp, ci: address pending issues from EVM simulation (#1063)

* add note

fix note

* add TestAppStateFn TestRandomAccounts

* marshal int slice to json

* add paramschange for enableCreate and enableCall

* AppStateFn -> StateFn

* add TestDecodeStore

* update github actions to run evm simulation

* add TestParamChanges

* add TestRandomizedGenState

* use go install for runsim

* resolve conflict

* use random gasCap to estimate gas

* use estimateGas to calculate max transferableAmount

* update godoc

* TestAppStateFn -> TestStateFn

* Update x/evm/simulation/genesis.go

* comment
