Move eval constants into consensus and normalize

I had an unwelcome discovery today that there are some constants in the TEAL evaluator that aren't in consensus.go and others that have different values...

For example MaxLogSize isn't in it:
https://github.com/algorand/go-algorand/blob/master/data/transactions/logic/eval.go#L59

And MaxLogCalls is 32 in eval.go but in consensus.go is something really really big --- https://github.com/algorand/go-algorand/blob/master/config/consensus.go#L536

I know it takes a long time to add stuff to consensus parameters, but please put this on your list

Also, I'd like MaxLogSize to be a bit bigger, like bigger than MaxAppTotalArgLen
