[Feature]: Make Protorev's call for multihop estimates skip TakerFee

[ValarDragon]

Protorev does not pay the taker fee in its swaps. We are unnecessarily computing the taker fee impact in protorev's multihop estimate logic. This costs us 1% of block sync's CPU time, and gives protorev less accurate internal estimates.

We should make a variant of this method:

osmosis/x/poolmanager/router.go

Line 229 in 49cd790

func (k Keeper) MultihopEstimateOutGivenExactAmountIn(

that does not include the taker fee for protorev. We will likely grow to doing more in such a method natively as we aim to make protorev have less costs with CL, but that can come later.
