Add event info for tx fee payment

[green-jay]

In order to check the currency in which a transaction was paid, currently one has to look up currencies.withdrawn event in the same block. (once https://github.com/galacticcouncil/hydration-node/issues/1032 is fixed)

We should always emit an event for EVM and non-EVM transactions which specifies the currency in which the fee was paid in.
