Upgrade network fees to support multiple assets

[woodenfurniture]

Currently our swappers and ui can only convey the concept of an "inbound network fee", however it's possible to have an "outbound network fee"
https://dev.thorchain.org/thorchain-dev/concepts/fees

We need to upgrade the interfaces, logic and UI to support this in order to accurately represent trades on thorchain (and lifi).

Upgrade the interfaces in lib/swapper/api.ts:

export type Fee = { requiresBalance: boolean } & AmountDisplayMeta

export type QuoteFeeData<T extends ChainId> = {
  networkFees: PartialRecord<AssetId, Fee> // fee(s) paid to the network from the fee asset (undefined if unknown)
  protocolFees: PartialRecord<AssetId, Fee> // fee(s) paid to the protocol(s)
} & ChainSpecificQuoteFeeData<T>

And then upgrade the UI to display multiple network fees, simiilar to how we do for protocol fees.

Dont forget to include this additional network fee in calculations that take fees into account!

Dont forget to upgrade thorchain swapper with the outbound fee as per the link above!

We should do this after #5171 is complete
